that at least two operations are necessary for having the command executed or the machine status changed.
_ The advantage of the invention is that the execution of a command cannot be initiated simply by pressing one single button of the first group. Ihis reduces the possibility of error. Since this also dispenses with the possibly complex ~_ _ process of canceling a given command, the operation of the device is also facilitated.
The required number of operations may differ depending on requirements; for example, it is possible for a command to be initiated only when the same command button is pressed twice. However, thepreferredconfi~uration i~ such that a separate ~put button is provided for initiating a command ~r a change in machine status.
In an embodiment of the invention in which the control de-vice exhibits at least one display papel, in particular a light-emitting diode display panel, there is a second group of pushbuttons for selecting at ~east:one item of informa-; tion which is to be displayed on the display panel. Thus, in an offset printing press with a plurality of servo-cylinders for each printing unit for setting the ink film thickness profile it is possible for the actual status of the settings of the individual servo-cylinders to be repre-sented on an ink zone display panel, or, instead, the setpoint status for a specific printing job can be shown, and ink ductor values (ink stripe length in circumferential direction of ink ductor roller) and register values can be indicated on a preerably numerical display panel. The pushbuttons of the second group are designed to enable the printer before and particularly while initiating a command by pressing a pushbutton of the first group to call u~ the relevant infor-mation on the display panel in order to check whether before the command is executed it is necessary to make any changes, ' 73~39 for example, in the position of the servo-cylinders~
In an embodiment of the invention the pushbuttons of the second group are each provided with a visually switchable indicator. In particular, the configuration may be such that when a pushbutton of the first group is actuated visual indicators of the second group which are permanent~y assigned ~ ~-to said actuatable pushbutton are actuated. The permanerlt assignment of the visual indicators, particularly LED's, is such that for all the individual commands or machine statuses which can be initiated by actuating a pushbutton of the first group the printer's attention is drawn to the push-button(s) of the second group whose information he should know before executing the initiated command in order, on the basis of his expert knowledge, to judge whether he wants to make any changes before the final execution of the command.
This simplifies the operation of the device for the printer since these L~D displays or other visual indicators dxaw his attention to the information which is<of relevance in each particular case. It is practical for the configuration to be such that ~uttons of the second group can also be actuated without pressing a command initiation button. It is also possible that after a button of the first group has been pressed only one single button of the second group is visually identified. In this case, it may be practical for the display belonging to thi button to appear automatically on the dis-play panel~ If other displays are also practical, it is pos-si~le for these other displays likewise to be made visible, also without the corresponding button of the second group previously having been visually identified. It may be prac-tical for the initiation of certain commands to make at least one of the buttons of the second group ineffective.
In an embodiment of the invention intended for a printing press with at least o~e printing unit there is a third group ~lZ~731~9 .~ .
o~ pushhuttons for making a command effective or ineffective for one or more printing units. In the specimen embodiment described later, although most commands are generally to be executed in the same manner for all printing units, there may 6till be cases where the printer, on the basis of his exper-ience, also wishes to make the aforementioned commands effec-tive only for some of the printing units. For the later-des-cribed "position" command, i,e. setting the ink film thickness profile and the ink ductor values, conversely, it will generallv be practical to execute the command separately for each individual printing unit. The configuration may be such that the command applies to all printing units unless specific printing units are specified. This group of pushbuttons may also be practical for printing presses with only one print-ing unit.
In an embodiment of the invention there is a fourth group of pushbuttons which are assigned to the printing colours being ; used and which can be assigned to the~pushbuttons of the third group. In general, although in an ~ffset printing press with a set number of print~ng units, for exam~le two printing units, the first printing unit will fre~uentl~ appl~
the colour black, and the second printing unit the other colour, it may be practical in individual cases to abandon such a rigid system, and the above-depicted embodiment of the invention allows the printer to assign the printing colours to the individual printing units as he desires.
Although internally the device described in the specimen embodiment works such that, in the final analysis, only the indivldual printing units are controlled, for example theix servo-c~linders for the ink film thickness profile, the depicted assignment of buttons of the fourth group which are in this case also identified as colour buttons makes it clear ~or the printer which colour belongs to which prlntiny unit, and embodiments of the invention may also enable the printer, for example when setting the ink film thickness profile and the ink ductor values ("position" command) to execute this `:
~2~3~9 ,_ :
. . ~
-- command for a 6pecific printing unit, for example printing ~_ unit No. one~ by pressing the colour button assigned to this printing unit.
,._ Apart from facilitating machine operation, the depicted colour assig~ment is also of importance when the control device is supplied with presetting values for the var:Lous ink film thickness profiles and ink ductor values by means of data transmission methods. In such a case the depicted colour assignment ensures that these supplied data cause the servo-cylinders to be adjusted only on those printing units which are assigned to the respective printing colour.
- ` In an embodiment of the invention the pushbuttons of the fourth group, lOe. the colour buttons, are each provided with a visual indicator, and the configuration is such that when a pushbutton of the first group is actuated visual inaicators ~f the fourth group permanently assigned to said pushbutton are actuated.
This embodiment may be practical for commandS in which a limitation of the command to a specific printing colour or equally to a specific printing u~it i-~ practical. This embodi-i ment can, therefore, be replaced with the same effect by a '!`';' different embodiment in which the visual indicators are assigned not to the printing colours, but to the printing units.
The last-described embodiment of the invention can be further developed such that a further visual indicator "all colours"
or~ compietely equivalent, an indicator "all printing units"
is provi~ed. In the later described specimen embodiment the confl~uration is ~uch that the last-mentioned indicator "all colours" or "all printing units" is not àssigned any particular pushbutton, but this indicakor is incorporated in the execution o~ the command if the printer does not limit the execution o~
;; the command to a ~pecifia colour or a specific printing unit.

_ - 6 _ In an embodiment of the in~e~tion in which the printer can select information for presentation on the display panel, the configuration is such that the values of the currentl~ dis-~J pla~ed information can be changed and the changed values o~ly become e~ecti~Je ~or 'che co~trol æ~e~ice i~ co~ar~d executionis initiated. The advantage of this is that, for example, the printer can change an ink film thickness profile as he thinks fit on the display panel, but he still has the possi-bility at all times of preventing the final setting of the thus changed ink film thickness profile. This embodiment is particularly important when information stored in the de~ice is overwritten, i.e. destroyed, by the definitive loading of the changed values.
In an embodiment ~f the invention a ~arning indicator is pro-vided for at least one of the buttons of the first grouD, said warning indicator becoming effective when the afore-mentioned button is actuated. The advantage of this embodi-ment is that the printer's attention càn be drawn to the fact that, prior to the execution of the command initiated by him, it would be practical be~orehand to execute one or more commands, particularly in order to prevent a loss of information. In an embodiment of the invention the warning indicator may exhibit a device for actuating a visual indi-cator which is assigned to at lcast one of the remaining buttons of the first group. In a further deve-lopment of this idea, the configuration may be such that the aforemen-tioned remaining buttons of the first group are visually ident~ied, particularly by an LED indicator, only when the printer presses a special button. In this last-mentioned case the warning indicator thus only makes the printer generally aware of the ifact that there are one or more commands which should be possibly be executed prior to the execution of the initiated command, and if the printer is not sure whether he has already initiated these commands or what commands these ~2~73~9 are, he c~n press the aforementioned button and see a visual display of these commands which may have to be execu~ed beforehand.
In embodiments of the invention it may be practical after the actuation of a button of the first group to render those buttons of the operator panel ineffective whose actuation is not advisable or might even lead to malfunctions. Usually, these are at least the other buttons of the first group.
In an embodiment of the invention which can also be realized independently of the initially described invention, there is a button for initiating a format shift command. This command is particularly useful when Printing jobs originally inten~ed for a smaller, i.e. narrower, printing press are to be car-ried out on a wider press. This command is also useful when a job intended for a narrow press is carried out on a wide press, twice on the same sheet side by side.
<
Further features of the invention relate to the different com~ands which are assigned to t4e pushbuttons of the first group and which are listed in the description and in the claims.
It is practical to provide a cancel button in order to be able to abort a command which has not yet been initiated for execution or a command which, although ~eing executed, is not yet completed.
In so far as reference is made above and in the ollowing des-cription to pushbuttons, it is pointed out expressly that pushbuttons are merely viewed as a very advantageous type of ac~uator by which the printer can communicate his instructions to the control device. However, all other devices suitable for the communication of instructions also fall within the scope of the invention, such as sensors, touch-buttons, rotary .

_ 8 --switches, rocker switches and actuation by light pen. It is considered especially important for the ease of operation by the printer that the individual controls, such as pushbuttons or similar, have their fixed position on the operator panel, f i.e. the printer need not enter his instructions via a type-writer keyboard, while possibly also taking account o in-structions which appear on a screen; although these last-depicted possibilities are not considered as advantageous as the fixed layout of the individual pushbuttons on an operator panel, these possibilities should not be excluded from the protection of the invention-Further features and advantages o the invention result fromthe ~ollowing description of a specimen embodiment of the invention with reference to the drawing, which shows essential details of the invention, and from the claims. The individual features may be realized individually or in any desired com-bination in an embodiment of the invention.

Fig. 1 shows the main part of the operator panel of a control device for a printing press. -:
Fig. 2 shows a display panel of the operator panel with further control buttons.
The operator panel 10 shown in Fig. 1 exhibits a first group of pushbuttons which are identified by the reference symbols 1-1 to 1-17. These pushbuttons are command initiation buttons, i.e. buttons for initiating a command and in one case also for initiating a machine status of the control device.
Furthermore, the operator panel 10 exhibits a second group of pushbuttons which are identified by the reference symbols 2-1 to 2-6 and which are used for selecting an item of infor-mation which is to be displayed on a display panel 20 in Fig. 2 .

and 50 in Fig. 1. A third group of pushbuttons exhibits, in the example, merely the two pushbuttons 3-1 and 3-2 which are identified by the numbers 1 and 2 and/ assuming that the control device is intended for a printing press with only two printing units, are assigned to these two printing units.
Underneath the buttons 3-1 and 3-2 there are four empty places in the operator panel 10 which can be provided with buttons corresponding to the number of printing units if the control device is intended for use with a printing press with a maximum of 6 printing units.
A fourth group of pushbuttons identified by the reference symbols 4-1 to 4-6 are used for assigning colours to the printing units and are referred to in the following as colour buttons for short. From top to bottom these colour buttons are assigned to the colours black, cyan, magenta, yell~w, there also being two additional colours identified by the letters X and Z. If two identical colours, e.g. black, are used in the printing press, then it is~practical to use button X (~-5) for the backing-up unit and button B (4-1~
or the recto unit so that it is~clea~ which colour belongs to which printing unit. ~ith the machine, for example, the colouxs black and cyan can be printed in a first run, and magenta and yellow in a second run for one and the same printing job.
In its uFper part the operator panel 1~ a~so exhibi~s an in-put button 5 with which a command input is completed and the execution of the command is initiated. It also exhibits a warning indicator button 6 and a cancel button 7 with which a command which has not yet been fully entered can be canceled and a command which is in the process of being executed but is not yet fully completed can be aborted. Furthermore, there ~s a key-operated switch 8 which makes it possible either to switch off the entire device, to switch it on or, in position `

"2" merely to activate the displays of the device whereby, however, no commands or control signals can be entered through the device.
Closely juxtaposed to each of the individual colour buttons is a light-emitting diode 14-1 to 14-6; there is also a light-emitting diode 14-7 which jointly indicates "all colours".
In the lower part of the operator panel there are command initiation buttons 1-13 and 1-14 for switching on a light pen; there are also control buttons 16-1 and 16-2 and a command initiation button 1-15. When button 1-15 is acutated the control buttons 16-1 and 1~-2 are used for the joint ~er-centage adjustment of the ink film thickness profile; other-wise for adjusting the ink ductor va~ue. The value of the percentage adjustment of the ink film thickness profile or ink ductor value is indicated on a numerical display 51.
Control buttons 17-1 and 17-2 as well as 18-1 and 18-2 are used for adjusting the circumferential registers or side registers of the printing press. The<adjustment for one single printing unit is performed in conjunction with one of the pushbuttons 3 or 4. If desired, using command initiation button 1-17 the shifting operation bv a desired number cf millimetres entered by buttons 17 and 18 by pressing the appropriate number of times can be extended to all registers.
By means of a command initiation button 1-17 all or individual registers can be reset to zero in conjunction with the buttons 3,~ and the lndicators 14-1 to 14-7. The positions and/or shift values of the respective registers can be indicated by means of numerical displays 52 and 53 or can be preselected by means o buttons 17,1~. The position of the circumferen-tial rçgisters is indicated by a light-emitting diode panel 26 with six columns each of 15 light-emitting diodes. Since frequently it is only the relative position of the registers in relation to each other which is of lnterest, by means of a control button 27 it is possible to reset to zero the dis-play for the circumferential registers irrespective of their actual position so that further changes can easily be executed.

, ' ' 1~73~9 The operator panel 10 also exhibits a light-emitting diode 30 for indicating a stoppage of the printing press in order to tell the printer that, for example, a register adjust~ent is not possible during this stoppage. Furthermore, there is a light-emitting diode 31 which indicates a failure of the computer 1 contained in the control device.
A numerical display 32 makes it possible in the event of faults or malfunctions to indicate to the printer the type of fault or malfunction.
The diode display panel 20 in Fig. i~ contains 32 columns each of 16 light-emitting diodes which are assigned to the individual ink zones of the printiny press whereby each ink zone exhibits a servo-cylinder for adjusting the ink film thic~ness profile.
The ink zones are identified by Z1 to Z32.
There are two control buttons 36-1 and 36-2 below each LED
column of the display panel 20. The light-emitting diode panel 20 serves not only to indicate the actual position of the servo-cylinders, but also seEVes other purposes. With the control buttons 36 the display of the light-emitting diode panel 20 can be changed for each individual column, and it is also possible for other, subsequently explained control operations to be effected.
The individual command initiation buttons 1~1 to 1-17 have the following significance:
Button 1-1: position command.
With this command the position of the servo-cylinders for the individual ink zones and the ink ductor values can be changed. r Button 1-2: correction control command With this command the printer can make the control device use ,. .
- l2-~2~73~g ' '~r . ':
externally supplied data and setting values calculated thexe - ~
from for the servo-cylinders and ink ductors for the once- -only ad~ustment of the servo-cylinders and ink ductors.
,~
Button 1-3: automatic correction command.
With this command it is possible to initiate the continuous automatic correction of the servo-cylinders and ink ductors as a function of data which are suPplied externally, for example from a measuring device, and which are converted into servo actuation values in the control device.
Button 1-4: colour assignment.
With this command it is possible for a standard assignment of colours to printing units stored in the control device (in the order of the printing units: black, cyan, mage~ta, yellow, X, Z; Fig. 1) to be changed if necessary. With the ; standard assignment each printing unit is assigned that colour which is identified by the colour button 4 which is located in the operator panel immediat~ly to the right of the corresponding printing unit button. When the colour as-- -signment command is initiated the prInter can, by simultan-eously pressing a printing unit button 3 and a colour button 4, preselect the desired alternative assignment and have it indicated (by lighting up of the pressed button) and can also have this implemented by input button S.
. ' , Button 1-5: ink reduction command.
With this command the ink film thickness can be brought to the value zero for all ink zones and any desired printing Ullits, and the ink ductor value can be brought to the maxi-mum value if it is desired to make the ductor and the follow-ing inking rollers free of ink as quickly as possible.
Button 1-6: format shift command.
With this command ink film thickness profiles can be shifted laterally zone by zone. This may be of relevance when :
- ` ~ . -` ~2~73~
_ 13-~ .
changing a job from a smaller press to a larger one because, in general, it is required that the printed sheets or webs run through the printing presssymmetrically, i.e. at equal J~ distances from the ends of the impression cylinders. If, for example, the presetting values for the individual ink zones are available on magnetic tape for a smaller press and these are entered in a larger press, then these entered values will not correspond to the required symmetrical posi-tion of the sheet in the press because in a smaller press having for example 16 ink zones, zones Z1 to Z16 corresPond to the full machine width whereas zones Z1 to Z16 on a press with 32 zones correspond to the left-hand half of the machine so that it is necessary to shift 8 ink zones to the right.
This command can also be used to transfer the above-assumed narrow format with a width of 16 z~nes to a larger press in that it is possible to work with double efficiency, i.e. the image which the small press has only printed once is printed twice side by side by the larger press~on a wide sheet or on a wide web.
After the actuation of the command initiation button 1-6 "format shift" this button itself lights up continuously, as do the light-emitting diode 14-7 "all colours" and button 2-4 "storage indicator", because a shift of format should normally concern all printing units and thus all colours and the format shift operation should always take place before positioning, i.e. before setting the servo-cylinders. With an optional button 36-1 it is possible to shift the pro~ile zone by zone from left to right whereby with each press of the button the profile moves on by one æone or, in the case of continuous actuation, there is a continuous shift. With an optional button 36-2 it is possible in a similar manner to shift the profile zone by zone to the left. The display which is pre-sent in the LED column of zone Z32 before shifting to the right appears after one shift step to the right in the LED
:~2~73~3~
lg colur~ Z1; in the same manner in a display memory connected to the LED display 20 the data contained there are cyclically shifted so that no data can be lost when shifting to right and left. When the correct shift has been performed, the printer actuates the input button 5, as a result of which the data so far stored in the display memory are loaded into a presetting memory of the device (the previous data are over-written) and are now available for setting the servo-cylinders whereby this setting operation is initiated by pressing the button 1-1 ~position).
Button 1-7: format limitation command.
This command is used for setting the ink film thickness to zero for all zones outside the format being printed and :Eor all printing units. This is done on a once-only basis and excludes the ink film thickness in these zones from computation operationsfor externally supplied data. After the actuation of button 1-7 which is lit permanently~after being actuated, any existing format limitation is indicated in that a special light-emitting diode 40 provided~below each LED colu~n of the display panel 20 lights up for all format-limited zones, where-as the light-emitting diodes 40 of the non-limited zones flash.
Other light-emitting diodes of the display panel 20 do not light up. In the operator panel 10 the light-emitting diode 14-7 "all colours" lights up whereby, in the specimen embodi-mentl no other LED displays appear. If button 36-1 is now actuated for a limited zone, the format limitation is canceled and the corresponding diode 40 flashes. At a oreviously non-limited zone is limited by actuating the corresponding button 36-2, and the corresponding light-emitting diode 40 makes the trans-ition from flashing to being lit continuously. The format is limited in such a way that when a button 36-2 in the right-hand half of the display panel is pressed the zone assigned to this button and all zones to the right of it are limited, 3~3~
_ 15 -whereas, when a button 36-2 in the left-hand half of the display panel 20 is pressed, this zone and all zones to the left of it are limited. The releasing of format-limited zones by pressing a button 36-1 is performed from the pres-sed button towards the format centre. Irrespective of the initia~ed command, the format-limited zones are visible in the correction display (button 2-2) in the diode row 40.
Button 1-8: zone disable or enable command.
This command makes it possi~le ~y actuating buttons 36 2 or 36-1 to disable or enable certain zones for the correction control and automatic correction commands. This disable which is visible in the correction display in the diode row 40 has no significance for other commandsO In particular, a manual adjustment is possible during the correction control and auto- r matic correction commands whereas, during these commands, the non-disabled zones are not manually adjustable. It is advis-able for this command to be executed separately for the in-dividual colours of a printing unit; t~erefore, after the button 1-8 has been pressed all those light-emitting diodes of diodes 14-1 to 14-6 flash which correspond to a colour which is acutally in use. ~he printer is now able, by pres-sing one of the buttons 4-1 to 4-6 or optionally also by pressing one of the printing unit buttons 3-1 or 3-2, to select that colour and thus also that printing unit for which zones are to be disabled or enabled. With these com-mand~, only that zone is disabled or enabled whose corres-ponding pushbutton 36-2 or 36-1 has been pressed.
Buttons 1-9, 1-11 and 1-12 correspond to the commands read in, record and erase tape and relate to control commands for a magnetic tape cartridge unit which is installed in the control device. If the printing press connected to the con-trol device is to be prepared for performing a new printing 121373~

job, then the presetting data for the servo-cylinders and ink ductor values which are stored on magnetic tape are, after actuation ~f pushbutton 1-9 read into the display '' memory which is assigned to the display panels 20 and'50.
On the light-emitting diode panel 20 and display panel 50 the printer can observe the entered values and, for example, can detect that an incorrect cartridge has been read in by mistake or that the data are incorrect. In such a case, the command is aborted by pressing the cancel button 7 with the result that the read-in data do not influence the working of the control device. If, on the other hand, the data are to be definitively loaded into the control device, the com~and is completed by pressing the input button 5.
Button 1-~0 causes the actual values for the positio~ of the servo-cylinaers ana in~ ducto~ ~o be stored into the memory of the control device. When the actual values have bee~
stored in this manner, they have the function of setpoint values for the position of the servo-cylinders and ink ductors during the further operation of the control device. The stor-'age of the actual values into the memory is also necessary '' if these actual values are subsequently to be stored through the command 1-11 "record on tape'; since the storage of data onto magnetic tape takes place from the memory.
The erase tape command is used to prevent old information remaining on a tape, thus possibly leading to faults in the setting'up of the press. In addition, the tape is now avail-able for the storage of other values.
It is indicated below which commands must be initiated for the warning button 6 to light up, and which of the further command initiation buttons flash in this case when warning bu'tton 6 is pressed.

.
The flashing of the above-mentioned buttons draws the atten-tion of the printer to the possible threat of data loss. I~, prior to the execution of the pre~ious~y initiated command, the printer would like to execute a cor~mand ~hich has been indicated by a flashing button, then he presses the cancel button 7 and initiates the desired cor~and. When the last-initiated command has finally been completed by pressing the input button 5, the originally initiated and, as depicted above, interrupted command must be initiated anew. The con-trol device thus does not initiate cor~mands independently, but all commands must be initiated by the printer. It is also possib]e to have the configuration such that when the corNmand `initiation button flashing after the actuation of the warning button 6 is pressed the command assi~ned to this button is initiated and the first-initiated cor~and is cancelled ~ithout it being necessary to actuate the cancel button. .-`` ~2~'73~9 _ 18 -When a command is initiated by pressing one of the command buttons 1-1,1-2,1-3,1-5,1-6,1-8 to 1-17 which correspond to commands which can be suitably executed for individual, ~?
several or all colours/printing units, the button itself lights up continuously as does the light-emitting diode 14-7; in addition, however, the light-emitting diodes 14-1 to 14-6 assigned to the colour buttons 4 also flash. If a printing unit button or colour button assigned to one of these flashing light-emitting diodes is pressed, then the originally flashing diode lights up continuously and the light-emitting diode 14-7 goes out. Further desired print-ing unit buttons or colour buttons can be actuated successively whereby the corresponding flashing light-emitting diode then always lights up continuously and thus informs the printer of the selected printing units/colours. The input ~utton 5 is then used for executing the command on the actuated printing units/colours. This selection possibility also exists, as is shown by the last-mentioned co~mands, for reading in from magnetic tape, recording and erasing ~he tape; partial erasing is therefore also possible.
For the format limitation command 1-7 such an extension of the selection possibility to individual printing units is not practi~al and, therefore, n~ne of the diodes 14-1 to 14-6 ~lashes.
For the ~ormat shift command 1-6, although generally a shift for all colours is useful, it may still be practical to ~er-form the shift operation merely for some of the colours.
The buttons 2-1 to 2-6 controlling the display on the light-emitting diode panel 20 have the following significance: r Button 2-1: density trend display; button 2-2: correction display;
., . .. ._ .. .. __ _ _ _ __ _ ~ ., . .... ~
~2B7;3~9 ,,~
Button 2-3: difference display; button 2-4: storage display;
Button 2-5: profile display; button 2-6: fine display. By pressing one of these above-mentioned buttons the correspond-ing information appears on the displays 20 and S0.
The density trend display sta~es whether the actual ink density values measured by a sheet measuring device di~fer from the respective setpoint value, and in ~hich direction and to what extent.
The correction display shows the externally supplied data and the values converted into control signals. The correction display switches on automatically when the commands "correc-ti~n control" or "automatic correction" are initiated. r The difference display shows the difference between setpoint and actual values for the position of the servo-cylinders and ink ductors values.
The storage display shows the setpoint values for the position of the servo-cylinders.
The profile display shows the actual position of the individual servo-cylinders for each individual zone in 16 steps. The additionally selectable fine display which makes use of the same light-emitting diodes as the profile display also shows the exact posit~on o the actual value between two neighboùr-ing llght-emitting diodes of the ~rofile display whereby, for the finè display, this distance between the light-emitting diodes used for the coarse display is extended to 16 light-emitting diodes. So that the profile display can be distin~uished from the fine display, the light-emitting diodes used for the fine display flicker, and they are lit slightly less brightly than the light-emitting diodes used for the profile display.
' `
~L2~7389 ~, - 2~ -'i.r ''' When the storage display, i.e. the display of the stored setpoint values, has been switched on by means of the command buttons 1-13 or 1-14 which represent two slightly different light pen commands, the printer can, on the light-emitting diode panel 20, change the displayed profile selected by button group 3 or 4 either by means of light pen or by means of buttons 36-1 and 36-2 and, by pressing the input button 5, he can enter the thus changed profile for the selected colour into the memory of the device as the new setpoint value. By presslng the button 2-5 for the profile display and, if necessary, also button 2-6 for the fine display, the printer can view the actual values for the position of the serv~-cylinders and ~an change these actual values as he thinks fit, likewise by means of the light pen or buttons 36-1 and 36-2 ;:
If, for one of the above-mentioned light pen commands, all colours are selected, an artificial profile appears on ~he light-emitting diode panel 20 in the form of an upward-pointing very blunt arrow tip which extends over the entire wi~th of the display panel 20 and whose tip ll-es in the area of the format centre in zones Z16 and Z17 in order to make the printer particularly aware of the fact that he has selected all colours/all printing units. For safety reasons, this dis-played profile cannot be loaded into the memory without further ado; on the contrary, command execution is only pos-sible when the artificial profile has been changed at at least two zones by the printer.
The ink ductor value appears on the numerical display 51.
This is the value of the ink ductor stroke in percent of the maximum ductor stroke which is possible on the printing press. If, in light pen mode, all printing units have been 3L2~373~9 2~ _ selected, there appears on the display 51 a mean value for the ink ductor value, in the example the nurnber 50. The load- ~
ing of this value into the memory, as a result of which all ~Ir~
ink ductors would be set to this value, is not possible simply by pressing the input button 5, but command execution is only possible when the value indicated by the display 51 has been acknowledged or changed. In the example this is done by buttons 16-1 and 16-2. When button 16 1 is tapped, the value indicated in the display 51 increases by 1. This value could now be loaded into the mernory by pressing the input button 5. ~f, on the other hand, the value 50 is to be entered, the printer briefly taps button 16-2, thus bring-ing the indicated value again to 50. He can now enter this value by pressing the input button 5. The selection of all colours is visually identified on the dispIay panel 51 by the flashing of the number shown in this display 51.
Immediately a button of the first group (1-1 to 1-17) is pressed it i5 lit continuously. Buttons of the operator panel 10 which after initiation of a corr~and are released for further actuation or light-e~itting diodes or displays assigned to the latter flash, after the pressing of the button the latter or the corresponding light-emitting diode or display is lit continuously. Ihe input button flashes after the initiation of a command, is lit after being pressed and goes out after the execution of the command. At this time all other LED displays in the executed command also go out, and the display status prior to initiation of the cor~mand is automatically selected again, i.e. the display panels show the information which was visible prior to initiation of the last command.
The buttons 2-1 to 2-6 are switched on by pressing and are switched off by renewed pressing or by another button 2. For ~2~73~9 - 2~ -,~............................... ..
easier identification, the buttons of the first group are orange, the buttons of the second t.o fourth groups white.
The depicted visual identification of previously actuated buttons, of buttons which may still re~uire actuation by the printer, and the depicted visual identification of displays on the display panels gives rise to a process of operator guidance; in operating the device, the printer is thus guided by the device itself. Ihis guidance facilitates the breaking-in of new personnel, prevents errors and leads to systematic working, .. _ . ~ _ .. . _ . _ _ , . _ _ . . . . . _
that at least two operations are necessary for having the command executed or the machine status changed.
_ The advantage of the invention is that the execution of a command cannot be initiated simply by pressing one single button of the first group. Ihis reduces the possibility of error. Since this also dispenses with the possibly complex ~_ _ process of canceling a given command, the operation of the device is also facilitated.
The required number of operations may differ depending on requirements; for example, it is possible for a command to be initiated only when the same command button is pressed twice. However, thepreferredconfi~uration i~ such that a separate ~put button is provided for initiating a command ~r a change in machine status.
In an embodiment of the invention in which the control de-vice exhibits at least one display papel, in particular a light-emitting diode display panel, there is a second group of pushbuttons for selecting at ~east:one item of informa-; tion which is to be displayed on the display panel. Thus, in an offset printing press with a plurality of servo-cylinders for each printing unit for setting the ink film thickness profile it is possible for the actual status of the settings of the individual servo-cylinders to be repre-sented on an ink zone display panel, or, instead, the setpoint status for a specific printing job can be shown, and ink ductor values (ink stripe length in circumferential direction of ink ductor roller) and register values can be indicated on a preerably numerical display panel. The pushbuttons of the second group are designed to enable the printer before and particularly while initiating a command by pressing a pushbutton of the first group to call u~ the relevant infor-mation on the display panel in order to check whether before the command is executed it is necessary to make any changes, ' 73~39 for example, in the position of the servo-cylinders~
In an embodiment of the invention the pushbuttons of the second group are each provided with a visually switchable indicator. In particular, the configuration may be such that when a pushbutton of the first group is actuated visual indicators of the second group which are permanent~y assigned ~ ~-to said actuatable pushbutton are actuated. The permanerlt assignment of the visual indicators, particularly LED's, is such that for all the individual commands or machine statuses which can be initiated by actuating a pushbutton of the first group the printer's attention is drawn to the push-button(s) of the second group whose information he should know before executing the initiated command in order, on the basis of his expert knowledge, to judge whether he wants to make any changes before the final execution of the command.
This simplifies the operation of the device for the printer since these L~D displays or other visual indicators dxaw his attention to the information which is<of relevance in each particular case. It is practical for the configuration to be such that ~uttons of the second group can also be actuated without pressing a command initiation button. It is also possible that after a button of the first group has been pressed only one single button of the second group is visually identified. In this case, it may be practical for the display belonging to thi button to appear automatically on the dis-play panel~ If other displays are also practical, it is pos-si~le for these other displays likewise to be made visible, also without the corresponding button of the second group previously having been visually identified. It may be prac-tical for the initiation of certain commands to make at least one of the buttons of the second group ineffective.
In an embodiment of the invention intended for a printing press with at least o~e printing unit there is a third group ~lZ~731~9 .~ .
o~ pushhuttons for making a command effective or ineffective for one or more printing units. In the specimen embodiment described later, although most commands are generally to be executed in the same manner for all printing units, there may 6till be cases where the printer, on the basis of his exper-ience, also wishes to make the aforementioned commands effec-tive only for some of the printing units. For the later-des-cribed "position" command, i,e. setting the ink film thickness profile and the ink ductor values, conversely, it will generallv be practical to execute the command separately for each individual printing unit. The configuration may be such that the command applies to all printing units unless specific printing units are specified. This group of pushbuttons may also be practical for printing presses with only one print-ing unit.
In an embodiment of the invention there is a fourth group of pushbuttons which are assigned to the printing colours being ; used and which can be assigned to the~pushbuttons of the third group. In general, although in an ~ffset printing press with a set number of print~ng units, for exam~le two printing units, the first printing unit will fre~uentl~ appl~
the colour black, and the second printing unit the other colour, it may be practical in individual cases to abandon such a rigid system, and the above-depicted embodiment of the invention allows the printer to assign the printing colours to the individual printing units as he desires.
Although internally the device described in the specimen embodiment works such that, in the final analysis, only the indivldual printing units are controlled, for example theix servo-c~linders for the ink film thickness profile, the depicted assignment of buttons of the fourth group which are in this case also identified as colour buttons makes it clear ~or the printer which colour belongs to which prlntiny unit, and embodiments of the invention may also enable the printer, for example when setting the ink film thickness profile and the ink ductor values ("position" command) to execute this `:
~2~3~9 ,_ :
. . ~
-- command for a 6pecific printing unit, for example printing ~_ unit No. one~ by pressing the colour button assigned to this printing unit.
,._ Apart from facilitating machine operation, the depicted colour assig~ment is also of importance when the control device is supplied with presetting values for the var:Lous ink film thickness profiles and ink ductor values by means of data transmission methods. In such a case the depicted colour assignment ensures that these supplied data cause the servo-cylinders to be adjusted only on those printing units which are assigned to the respective printing colour.
- ` In an embodiment of the invention the pushbuttons of the fourth group, lOe. the colour buttons, are each provided with a visual indicator, and the configuration is such that when a pushbutton of the first group is actuated visual inaicators ~f the fourth group permanently assigned to said pushbutton are actuated.
This embodiment may be practical for commandS in which a limitation of the command to a specific printing colour or equally to a specific printing u~it i-~ practical. This embodi-i ment can, therefore, be replaced with the same effect by a '!`';' different embodiment in which the visual indicators are assigned not to the printing colours, but to the printing units.
The last-described embodiment of the invention can be further developed such that a further visual indicator "all colours"
or~ compietely equivalent, an indicator "all printing units"
is provi~ed. In the later described specimen embodiment the confl~uration is ~uch that the last-mentioned indicator "all colours" or "all printing units" is not àssigned any particular pushbutton, but this indicakor is incorporated in the execution o~ the command if the printer does not limit the execution o~
;; the command to a ~pecifia colour or a specific printing unit.

_ - 6 _ In an embodiment of the in~e~tion in which the printer can select information for presentation on the display panel, the configuration is such that the values of the currentl~ dis-~J pla~ed information can be changed and the changed values o~ly become e~ecti~Je ~or 'che co~trol æ~e~ice i~ co~ar~d executionis initiated. The advantage of this is that, for example, the printer can change an ink film thickness profile as he thinks fit on the display panel, but he still has the possi-bility at all times of preventing the final setting of the thus changed ink film thickness profile. This embodiment is particularly important when information stored in the de~ice is overwritten, i.e. destroyed, by the definitive loading of the changed values.
In an embodiment ~f the invention a ~arning indicator is pro-vided for at least one of the buttons of the first grouD, said warning indicator becoming effective when the afore-mentioned button is actuated. The advantage of this embodi-ment is that the printer's attention càn be drawn to the fact that, prior to the execution of the command initiated by him, it would be practical be~orehand to execute one or more commands, particularly in order to prevent a loss of information. In an embodiment of the invention the warning indicator may exhibit a device for actuating a visual indi-cator which is assigned to at lcast one of the remaining buttons of the first group. In a further deve-lopment of this idea, the configuration may be such that the aforemen-tioned remaining buttons of the first group are visually ident~ied, particularly by an LED indicator, only when the printer presses a special button. In this last-mentioned case the warning indicator thus only makes the printer generally aware of the ifact that there are one or more commands which should be possibly be executed prior to the execution of the initiated command, and if the printer is not sure whether he has already initiated these commands or what commands these ~2~73~9 are, he c~n press the aforementioned button and see a visual display of these commands which may have to be execu~ed beforehand.
In embodiments of the invention it may be practical after the actuation of a button of the first group to render those buttons of the operator panel ineffective whose actuation is not advisable or might even lead to malfunctions. Usually, these are at least the other buttons of the first group.
In an embodiment of the invention which can also be realized independently of the initially described invention, there is a button for initiating a format shift command. This command is particularly useful when Printing jobs originally inten~ed for a smaller, i.e. narrower, printing press are to be car-ried out on a wider press. This command is also useful when a job intended for a narrow press is carried out on a wide press, twice on the same sheet side by side.
<
Further features of the invention relate to the different com~ands which are assigned to t4e pushbuttons of the first group and which are listed in the description and in the claims.
It is practical to provide a cancel button in order to be able to abort a command which has not yet been initiated for execution or a command which, although ~eing executed, is not yet completed.
In so far as reference is made above and in the ollowing des-cription to pushbuttons, it is pointed out expressly that pushbuttons are merely viewed as a very advantageous type of ac~uator by which the printer can communicate his instructions to the control device. However, all other devices suitable for the communication of instructions also fall within the scope of the invention, such as sensors, touch-buttons, rotary .

It is considered especially important for the ease of operation by the printer that the individual controls, such as pushbuttons or similar, have their fixed position on the operator panel, f i.e. the printer need not enter his instructions via a type-writer keyboard, while possibly also taking account o in-structions which appear on a screen; although these last-depicted possibilities are not considered as advantageous as the fixed layout of the individual pushbuttons on an operator panel, these possibilities should not be excluded from the protection of the invention-Further features and advantages o the invention result fromthe ~ollowing description of a specimen embodiment of the invention with reference to the drawing, which shows essential details of the invention, and from the claims. The individual features may be realized individually or in any desired com-bination in an embodiment of the invention.

Fig. 1 shows the main part of the operator panel of a control device for a printing press. -:
Fig. 2 shows a display panel of the operator panel with further control buttons.
The operator panel 10 shown in Fig. 1 exhibits a first group of pushbuttons which are identified by the reference symbols 1-1 to 1-17. These pushbuttons are command initiation buttons, i.e. buttons for initiating a command and in one case also for initiating a machine status of the control device.
Furthermore, the operator panel 10 exhibits a second group of pushbuttons which are identified by the reference symbols 2-1 to 2-6 and which are used for selecting an item of infor-mation which is to be displayed on a display panel 20 in Fig. 2 .

and 50 in Fig. 1. A third group of pushbuttons exhibits, in the example, merely the two pushbuttons 3-1 and 3-2 which are identified by the numbers 1 and 2 and/ assuming that the control device is intended for a printing press with only two printing units, are assigned to these two printing units.
Underneath the buttons 3-1 and 3-2 there are four empty places in the operator panel 10 which can be provided with buttons corresponding to the number of printing units if the control device is intended for use with a printing press with a maximum of 6 printing units.
A fourth group of pushbuttons identified by the reference symbols 4-1 to 4-6 are used for assigning colours to the printing units and are referred to in the following as colour buttons for short. From top to bottom these colour buttons are assigned to the colours black, cyan, magenta, yell~w, there also being two additional colours identified by the letters X and Z. If two identical colours, e.g. black, are used in the printing press, then it is~practical to use button X (~-5) for the backing-up unit and button B (4-1~
or the recto unit so that it is~clea~ which colour belongs to which printing unit. ~ith the machine, for example, the colouxs black and cyan can be printed in a first run, and magenta and yellow in a second run for one and the same printing job.
In its uFper part the operator panel 1~ a~so exhibi~s an in-put button 5 with which a command input is completed and the execution of the command is initiated. It also exhibits a warning indicator button 6 and a cancel button 7 with which a command which has not yet been fully entered can be canceled and a command which is in the process of being executed but is not yet fully completed can be aborted. Furthermore, there ~s a key-operated switch 8 which makes it possible either to switch off the entire device, to switch it on or, in position `

"2" merely to activate the displays of the device whereby, however, no commands or control signals can be entered through the device.
Closely juxtaposed to each of the individual colour buttons is a light-emitting diode 14-1 to 14-6; there is also a light-emitting diode 14-7 which jointly indicates "all colours".
In the lower part of the operator panel there are command initiation buttons 1-13 and 1-14 for switching on a light pen; there are also control buttons 16-1 and 16-2 and a command initiation button 1-15. When button 1-15 is acutated the control buttons 16-1 and 1~-2 are used for the joint ~er-centage adjustment of the ink film thickness profile; other-wise for adjusting the ink ductor va~ue. The value of the percentage adjustment of the ink film thickness profile or ink ductor value is indicated on a numerical display 51.
Control buttons 17-1 and 17-2 as well as 18-1 and 18-2 are used for adjusting the circumferential registers or side registers of the printing press. The<adjustment for one single printing unit is performed in conjunction with one of the pushbuttons 3 or 4. If desired, using command initiation button 1-17 the shifting operation bv a desired number cf millimetres entered by buttons 17 and 18 by pressing the appropriate number of times can be extended to all registers.
By means of a command initiation button 1-17 all or individual registers can be reset to zero in conjunction with the buttons 3,~ and the lndicators 14-1 to 14-7. The positions and/or shift values of the respective registers can be indicated by means of numerical displays 52 and 53 or can be preselected by means o buttons 17,1~. The position of the circumferen-tial rçgisters is indicated by a light-emitting diode panel 26 with six columns each of 15 light-emitting diodes. Since frequently it is only the relative position of the registers in relation to each other which is of lnterest, by means of a control button 27 it is possible to reset to zero the dis-play for the circumferential registers irrespective of their actual position so that further changes can easily be executed.

, ' ' 1~73~9 The operator panel 10 also exhibits a light-emitting diode 30 for indicating a stoppage of the printing press in order to tell the printer that, for example, a register adjust~ent is not possible during this stoppage. Furthermore, there is a light-emitting diode 31 which indicates a failure of the computer 1 contained in the control device.
A numerical display 32 makes it possible in the event of faults or malfunctions to indicate to the printer the type of fault or malfunction.
The diode display panel 20 in Fig. i~ contains 32 columns each of 16 light-emitting diodes which are assigned to the individual ink zones of the printiny press whereby each ink zone exhibits a servo-cylinder for adjusting the ink film thic~ness profile.
The ink zones are identified by Z1 to Z32.
There are two control buttons 36-1 and 36-2 below each LED
column of the display panel 20. The light-emitting diode panel 20 serves not only to indicate the actual position of the servo-cylinders, but also seEVes other purposes. With the control buttons 36 the display of the light-emitting diode panel 20 can be changed for each individual column, and it is also possible for other, subsequently explained control operations to be effected.
The individual command initiation buttons 1~1 to 1-17 have the following significance:
Button 1-1: position command.
With this command the position of the servo-cylinders for the individual ink zones and the ink ductor values can be changed. r Button 1-2: correction control command With this command the printer can make the control device use ,. .
- l2-~2~73~g ' '~r . ':
externally supplied data and setting values calculated thexe - ~
from for the servo-cylinders and ink ductors for the once- -only ad~ustment of the servo-cylinders and ink ductors.
,~
Button 1-3: automatic correction command.
With this command it is possible to initiate the continuous automatic correction of the servo-cylinders and ink ductors as a function of data which are suPplied externally, for example from a measuring device, and which are converted into servo actuation values in the control device.
Button 1-4: colour assignment.
With this command it is possible for a standard assignment of colours to printing units stored in the control device (in the order of the printing units: black, cyan, mage~ta, yellow, X, Z; Fig. 1) to be changed if necessary. With the ; standard assignment each printing unit is assigned that colour which is identified by the colour button 4 which is located in the operator panel immediat~ly to the right of the corresponding printing unit button. When the colour as-- -signment command is initiated the prInter can, by simultan-eously pressing a printing unit button 3 and a colour button 4, preselect the desired alternative assignment and have it indicated (by lighting up of the pressed button) and can also have this implemented by input button S.
. ' , Button 1-5: ink reduction command.
With this command the ink film thickness can be brought to the value zero for all ink zones and any desired printing Ullits, and the ink ductor value can be brought to the maxi-mum value if it is desired to make the ductor and the follow-ing inking rollers free of ink as quickly as possible.
Button 1-6: format shift command.
With this command ink film thickness profiles can be shifted laterally zone by zone. This may be of relevance when :
- ` ~ . -` ~2~73~
_ 13-~ .
changing a job from a smaller press to a larger one because, in general, it is required that the printed sheets or webs run through the printing presssymmetrically, i.e. at equal J~ distances from the ends of the impression cylinders. If, for example, the presetting values for the individual ink zones are available on magnetic tape for a smaller press and these are entered in a larger press, then these entered values will not correspond to the required symmetrical posi-tion of the sheet in the press because in a smaller press having for example 16 ink zones, zones Z1 to Z16 corresPond to the full machine width whereas zones Z1 to Z16 on a press with 32 zones correspond to the left-hand half of the machine so that it is necessary to shift 8 ink zones to the right.
This command can also be used to transfer the above-assumed narrow format with a width of 16 z~nes to a larger press in that it is possible to work with double efficiency, i.e. the image which the small press has only printed once is printed twice side by side by the larger press~on a wide sheet or on a wide web.
After the actuation of the command initiation button 1-6 "format shift" this button itself lights up continuously, as do the light-emitting diode 14-7 "all colours" and button 2-4 "storage indicator", because a shift of format should normally concern all printing units and thus all colours and the format shift operation should always take place before positioning, i.e. before setting the servo-cylinders. With an optional button 36-1 it is possible to shift the pro~ile zone by zone from left to right whereby with each press of the button the profile moves on by one æone or, in the case of continuous actuation, there is a continuous shift. With an optional button 36-2 it is possible in a similar manner to shift the profile zone by zone to the left. The display which is pre-sent in the LED column of zone Z32 before shifting to the right appears after one shift step to the right in the LED
:~2~73~3~
lg colur~ Z1; in the same manner in a display memory connected to the LED display 20 the data contained there are cyclically shifted so that no data can be lost when shifting to right and left. When the correct shift has been performed, the printer actuates the input button 5, as a result of which the data so far stored in the display memory are loaded into a presetting memory of the device (the previous data are over-written) and are now available for setting the servo-cylinders whereby this setting operation is initiated by pressing the button 1-1 ~position).
Button 1-7: format limitation command.
This command is used for setting the ink film thickness to zero for all zones outside the format being printed and :Eor all printing units. This is done on a once-only basis and excludes the ink film thickness in these zones from computation operationsfor externally supplied data. After the actuation of button 1-7 which is lit permanently~after being actuated, any existing format limitation is indicated in that a special light-emitting diode 40 provided~below each LED colu~n of the display panel 20 lights up for all format-limited zones, where-as the light-emitting diodes 40 of the non-limited zones flash.
Other light-emitting diodes of the display panel 20 do not light up. In the operator panel 10 the light-emitting diode 14-7 "all colours" lights up whereby, in the specimen embodi-mentl no other LED displays appear. If button 36-1 is now actuated for a limited zone, the format limitation is canceled and the corresponding diode 40 flashes. At a oreviously non-limited zone is limited by actuating the corresponding button 36-2, and the corresponding light-emitting diode 40 makes the trans-ition from flashing to being lit continuously. The format is limited in such a way that when a button 36-2 in the right-hand half of the display panel is pressed the zone assigned to this button and all zones to the right of it are limited, 3~3~
_ 15 -whereas, when a button 36-2 in the left-hand half of the display panel 20 is pressed, this zone and all zones to the left of it are limited. The releasing of format-limited zones by pressing a button 36-1 is performed from the pres-sed button towards the format centre. Irrespective of the initia~ed command, the format-limited zones are visible in the correction display (button 2-2) in the diode row 40.
Button 1-8: zone disable or enable command.
This command makes it possi~le ~y actuating buttons 36 2 or 36-1 to disable or enable certain zones for the correction control and automatic correction commands. This disable which is visible in the correction display in the diode row 40 has no significance for other commandsO In particular, a manual adjustment is possible during the correction control and auto- r matic correction commands whereas, during these commands, the non-disabled zones are not manually adjustable. It is advis-able for this command to be executed separately for the in-dividual colours of a printing unit; t~erefore, after the button 1-8 has been pressed all those light-emitting diodes of diodes 14-1 to 14-6 flash which correspond to a colour which is acutally in use. ~he printer is now able, by pres-sing one of the buttons 4-1 to 4-6 or optionally also by pressing one of the printing unit buttons 3-1 or 3-2, to select that colour and thus also that printing unit for which zones are to be disabled or enabled. With these com-mand~, only that zone is disabled or enabled whose corres-ponding pushbutton 36-2 or 36-1 has been pressed.
Buttons 1-9, 1-11 and 1-12 correspond to the commands read in, record and erase tape and relate to control commands for a magnetic tape cartridge unit which is installed in the control device. If the printing press connected to the con-trol device is to be prepared for performing a new printing 121373~

' j.r .
job, then the presetting data for the servo-cylinders and ink ductor values which are stored on magnetic tape are, after actuation ~f pushbutton 1-9 read into the display '' memory which is assigned to the display panels 20 and'50.
On the light-emitting diode panel 20 and display panel 50 the printer can observe the entered values and, for example, can detect that an incorrect cartridge has been read in by mistake or that the data are incorrect. In such a case, the command is aborted by pressing the cancel button 7 with the result that the read-in data do not influence the working of the control device. If, on the other hand, the data are to be definitively loaded into the control device, the com~and is completed by pressing the input button 5.
Button 1-~0 causes the actual values for the positio~ of the servo-cylinaers ana in~ ducto~ ~o be stored into the memory of the control device. When the actual values have bee~
stored in this manner, they have the function of setpoint values for the position of the servo-cylinders and ink ductors during the further operation of the control device. The stor-'age of the actual values into the memory is also necessary '' if these actual values are subsequently to be stored through the command 1-11 "record on tape'; since the storage of data onto magnetic tape takes place from the memory.
The erase tape command is used to prevent old information remaining on a tape, thus possibly leading to faults in the setting'up of the press. In addition, the tape is now avail-able for the storage of other values.
It is indicated below which commands must be initiated for the warning button 6 to light up, and which of the further command initiation buttons flash in this case when warning bu'tton 6 is pressed.

ton 1-g Iread in command): after the warning ~utton 6 is pressed the button 1-11 flashes (rec~rd command).
.
The flashing of the above-mentioned buttons draws the atten-tion of the printer to the possible threat of data loss. I~, prior to the execution of the pre~ious~y initiated command, the printer would like to execute a cor~mand ~hich has been indicated by a flashing button, then he presses the cancel button 7 and initiates the desired cor~and. When the last-initiated command has finally been completed by pressing the input button 5, the originally initiated and, as depicted above, interrupted command must be initiated anew. The con-trol device thus does not initiate cor~mands independently, but all commands must be initiated by the printer. It is also possib]e to have the configuration such that when the corNmand `initiation button flashing after the actuation of the warning button 6 is pressed the command assi~ned to this button is initiated and the first-initiated cor~and is cancelled ~ithout it being necessary to actuate the cancel button. .-`` ~2~'73~9 _ 18 -When a command is initiated by pressing one of the command buttons 1-1,1-2,1-3,1-5,1-6,1-8 to 1-17 which correspond to commands which can be suitably executed for individual, ~?
several or all colours/printing units, the button itself lights up continuously as does the light-emitting diode 14-7; in addition, however, the light-emitting diodes 14-1 to 14-6 assigned to the colour buttons 4 also flash. If a printing unit button or colour button assigned to one of these flashing light-emitting diodes is pressed, then the originally flashing diode lights up continuously and the light-emitting diode 14-7 goes out. Further desired print-ing unit buttons or colour buttons can be actuated successively whereby the corresponding flashing light-emitting diode then always lights up continuously and thus informs the printer of the selected printing units/colours. The input ~utton 5 is then used for executing the command on the actuated printing units/colours. This selection possibility also exists, as is shown by the last-mentioned co~mands, for reading in from magnetic tape, recording and erasing ~he tape; partial erasing is therefore also possible.
For the format limitation command 1-7 such an extension of the selection possibility to individual printing units is not practi~al and, therefore, n~ne of the diodes 14-1 to 14-6 ~lashes.
For the ~ormat shift command 1-6, although generally a shift for all colours is useful, it may still be practical to ~er-form the shift operation merely for some of the colours.
The buttons 2-1 to 2-6 controlling the display on the light-emitting diode panel 20 have the following significance: r Button 2-1: density trend display; button 2-2: correction display;
., . .. ._ .. .. __ _ _ _ __ _ ~ ., . .... ~
~2B7;3~9 ,,~
Button 2-3: difference display; button 2-4: storage display;
Button 2-5: profile display; button 2-6: fine display. By pressing one of these above-mentioned buttons the correspond-ing information appears on the displays 20 and S0.
The density trend display sta~es whether the actual ink density values measured by a sheet measuring device di~fer from the respective setpoint value, and in ~hich direction and to what extent.
The correction display shows the externally supplied data and the values converted into control signals. The correction display switches on automatically when the commands "correc-ti~n control" or "automatic correction" are initiated. r The difference display shows the difference between setpoint and actual values for the position of the servo-cylinders and ink ductors values.
The storage display shows the setpoint values for the position of the servo-cylinders.
The profile display shows the actual position of the individual servo-cylinders for each individual zone in 16 steps. The additionally selectable fine display which makes use of the same light-emitting diodes as the profile display also shows the exact posit~on o the actual value between two neighboùr-ing llght-emitting diodes of the ~rofile display whereby, for the finè display, this distance between the light-emitting diodes used for the coarse display is extended to 16 light-emitting diodes. So that the profile display can be distin~uished from the fine display, the light-emitting diodes used for the fine display flicker, and they are lit slightly less brightly than the light-emitting diodes used for the profile display.
' `
~L2~7389 ~, - 2~ -'i.r ''' When the storage display, i.e. the display of the stored setpoint values, has been switched on by means of the command buttons 1-13 or 1-14 which represent two slightly different light pen commands, the printer can, on the light-emitting diode panel 20, change the displayed profile selected by button group 3 or 4 either by means of light pen or by means of buttons 36-1 and 36-2 and, by pressing the input button 5, he can enter the thus changed profile for the selected colour into the memory of the device as the new setpoint value. By presslng the button 2-5 for the profile display and, if necessary, also button 2-6 for the fine display, the printer can view the actual values for the position of the serv~-cylinders and ~an change these actual values as he thinks fit, likewise by means of the light pen or buttons 36-1 and 36-2 ;:
If, for one of the above-mentioned light pen commands, all colours are selected, an artificial profile appears on ~he light-emitting diode panel 20 in the form of an upward-pointing very blunt arrow tip which extends over the entire wi~th of the display panel 20 and whose tip ll-es in the area of the format centre in zones Z16 and Z17 in order to make the printer particularly aware of the fact that he has selected all colours/all printing units. For safety reasons, this dis-played profile cannot be loaded into the memory without further ado; on the contrary, command execution is only pos-sible when the artificial profile has been changed at at least two zones by the printer.
The ink ductor value appears on the numerical display 51.
This is the value of the ink ductor stroke in percent of the maximum ductor stroke which is possible on the printing press. If, in light pen mode, all printing units have been 3L2~373~9 2~ _ selected, there appears on the display 51 a mean value for the ink ductor value, in the example the nurnber 50. The load- ~
ing of this value into the memory, as a result of which all ~Ir~
ink ductors would be set to this value, is not possible simply by pressing the input button 5, but command execution is only possible when the value indicated by the display 51 has been acknowledged or changed. In the example this is done by buttons 16-1 and 16-2. When button 16 1 is tapped, the value indicated in the display 51 increases by 1. This value could now be loaded into the mernory by pressing the input button 5. ~f, on the other hand, the value 50 is to be entered, the printer briefly taps button 16-2, thus bring-ing the indicated value again to 50. He can now enter this value by pressing the input button 5. The selection of all colours is visually identified on the dispIay panel 51 by the flashing of the number shown in this display 51.
Immediately a button of the first group (1-1 to 1-17) is pressed it i5 lit continuously. Buttons of the operator panel 10 which after initiation of a corr~and are released for further actuation or light-e~itting diodes or displays assigned to the latter flash, after the pressing of the button the latter or the corresponding light-emitting diode or display is lit continuously. Ihe input button flashes after the initiation of a command, is lit after being pressed and goes out after the execution of the command. At this time all other LED displays in the executed command also go out, and the display status prior to initiation of the cor~mand is automatically selected again, i.e. the display panels show the information which was visible prior to initiation of the last command.
The buttons 2-1 to 2-6 are switched on by pressing and are switched off by renewed pressing or by another button 2. For ~2~73~9 - 2~ -,~............................... ..
easier identification, the buttons of the first group are orange, the buttons of the second t.o fourth groups white.
The depicted visual identification of previously actuated buttons, of buttons which may still re~uire actuation by the printer, and the depicted visual identification of displays on the display panels gives rise to a process of operator guidance; in operating the device, the printer is thus guided by the device itself. Ihis guidance facilitates the breaking-in of new personnel, prevents errors and leads to systematic working, .. _ . ~ _ .. . _ . _ _ , . _ _ . . . . . _
