The invention relates to a production planning and production control system of a digital printing press and at least one downstream of the digital printing machine further processing device according to the preamble of claim 1. The invention further relates to a further processing planning module of such a production planning and production control system.

Printers are increasingly using digital printing presses. In contrast to conventional offset printing machines, digital printing machines are particularly suitable for printing print jobs when a large number of alternating print jobs have to be printed in small print runs. For example, in digital printing presses, the exposure of printing plates required by offset printing machines and the replacement of printing plates between different print jobs are eliminated. This then eliminates set-up times at the printing press.

It is already known in the art that a digital press includes a production planning and production control system to plan and control the printing of print jobs on the digital press. Thus, production planning and production control systems of a printing machine known from practice have a digital printing planning module and a printing press computer.

The digital print scheduling module receives print job data from print jobs to be printed, checks the received print job data and thus the print jobs for printability on the digital press, and generates print control data based on the print job data for valid and printable jobs. This print control data provides the digital printing scheduling module to the printing machine computer, wherein the printing press computer converts the print control data of the valid print jobs into drive data for individual modules, in particular drive data for printing units or print heads, of the printing press to ultimately print valid print jobs on the digital press.

Then, when the digital printing machine at least one further processing device, such as a cutting device and / or a folding device and / or a stapling device is arranged downstream, the or each further processing device must be controlled. So far, it is not possible to incorporate a further processing device automatically in the data flow of the production planning and production control system, rather takes place in known from practice digital printing machines controlling the or each of the digital press downstream processing device either manually or by means of printed on a substrate control marks, such as using barcodes. This limits the degree of automation when printing with digital presses.

The production planning and production control system according to the invention comprises a further processing planning module, wherein the further processing planning module receives imposition data of the valid print jobs that the digital printing scheduling module generates for each valid print job, and checks whether the respective imposition scheme is processable using the or each downstream printing processing device, wherein the further processing scheduling module, if the imposition is uneditable, communicates a status message to the digital printing scheduling module that prohibits printing of the respective print job on the digital press, and if the imposition pattern is editable, the finishing scheduling module transmits a status message to the digital printing scheduling module that prints the respective one Print job on the digital press allows, and on the other hand Next processing control data generated and transmitted to a further processing computer directly or indirectly, which generates therefrom control data for the or each further processing device.

The present invention proposes a production planning and production control system by means of which the or each of the digital printing press downstream processing device can be automatically integrated into the data flow of the production planning and production control system. This can increase the degree of automation of a production planning and production control system of a digital press. Using the production planning and invention Production control system, the or each of the digital printing press downstream processing device is automatically controlled, as well as corresponding control data for the or each finishing device are automatically generated. Thus, the further processing or post-processing of printed products printed on a digital press is integrated into the data flow, which can increase the efficiency of digital printing.

According to an advantageous development of the invention, production possibilities for the or each digital press downstream processing device are stored in the further processing planning module, wherein the further processing planning module matches the imposition of a print job with the production options and thus verifies whether the imposition scheme is editable using the or each of the digital press downstream processing device , The above check, whether an imposition scheme of a print job on the or each of the digital press downstream processing device is editable, is automated with little effort by the finishing processing module feasible.

The printing press computer and the further processing computer preferably exchange synchronization data. Then, when the printing machine computer and the further processing computer exchange synchronization data, a particularly preferred operation of the digital printing machine is tuned to the or each of the digital printing press downstream processing device automatically possible.

1 FIG. 2: a diagram of a production planning and production control system of a digital printing press and with at least one further processing device downstream of the digital printing press.

The present invention relates to a production planning and production control system of a digital printing machine and at least one downstream of the digital printing machine further processing device.

1 shows very schematically the basic structure of a production planning and production control system according to the invention 10 together with a digital printing machine 11 and with the digital press 11 downstream processing facilities 12 , 1 can be taken that the digital printing machine 11 is designed as a web-fed printing press, which serves to print a ready-to-use as stock roll BR printing material BB. 1 shows a roll changer RW, on which a Bedruckstoffrolle BR is provided, wherein a printing substrate BB is withdrawn by means of a feed EW from the substrate roll BR and printing units DE of the digital printing press 11 for printing the same is supplied. In 1 a total of eight printing units DE or print heads are shown, by means of which the printing substrate BB can be printed on both sides in color. The in the digital printing press 11 Printed substrate BB can be produced by means of a drawing device ZE from the field of digital printing press 11 pulled out and into the area of the or each of the digital printing press 11 downstream processing device 12 be retracted, in 1 as further processing 12 schematized a cutting device SE and a folding device FE are shown. By means of the cutting device SE, individual copies can be separated from the printed printing material web BB by cross-cutting, which can be provided with the aid of the folding unit FE with a longitudinal fold and / or transverse fold.

At this point it should be noted that the above-mentioned components of the digital printing press 11 and the processing facilities 12 purely exemplary nature are.

The production planning and production control system 10 has a digital print planning module 13 which receives print job data from print jobs to be printed. This print job data 14 the print jobs to be printed which the digital print scheduling module 13 preferably are in PDF format.

The digital printing planning module 13 which the print job data 14 receives, checks the print job data 14 and thus the print jobs on their printability on the digital printing machine 11 and generates based on this verification of the print job data 14 Print control data 15 for valid and printable jobs, where the digital print scheduling module 13 this pressure control data 15 a printing machine computer 16 of the production planning and production control system 10 provides. This pressure control data 15 For example, there are print data streams in the form of IPDS data or AFF data.

The printing machine computer 16 receives the pressure control data 15 from the digital print planning module 13 and generates driving data from this 17 for the individual components of the printing press 11 to valid print jobs on the digital press 11 to print. All the above steps or functions of the production planning and production control system 10 which the digital printing planning module 13 and the printing machine computer 16 deploy, expire automatically.

The production planning and production control system according to the invention 10 further comprises a further processing planning module 18 , wherein the further processing planning module 18 Ausschießschemadaten 19 which the digital printing planning module 13 automatically based on the print job data 14 generated from valid print jobs or which the print job data 14 include, receives automatically and automatically checks.

The imposition schemata 19 especially in JDF format. The communication between the digital printing planning module 13 and the finishing processing module 18 preferably by JMF data.

The further processing planning module checks 18 Whether the particular imposition of a print job using the or each digital press 11 downstream processing device 12 is editable, namely in the sense of the possibilities of or each finishing device 12 from a machine engineering point of view. Then, if the finishing processing module 18 determines that an imposition is not editable, it automatically generates a status message 20 and transmits the same to the digital printing scheduling module 13 to print each print job on the press 11 to stop, because then one on the press 11 Printed print job in the field of or each finishing device 12 can not be edited.

Then, on the other hand, if the further processing planning module 18 determines that an imposition scheme of a print job on the finishing device 12 can be edited, it transmits a corresponding status message 21 to the digital printing planning module 13 to print each job on the digital press 11 permit. Furthermore, the further processing planning module generates 18 then, if it determines that an imposition scheme can be edited, further processing control data 22 and automatically transmits them directly to a further processing computer 23 , wherein the further processing computer 23 from the further processing control data 22 driving data 24 for the respective further processing device 12 automatically generated, so that in case of multiple finishing device 12 the same can be controlled in parallel or simultaneously.

The processing control data 22 are available in a proprietary format of the machine control.

The of the further processing planning module 18 for editable imposition schemes and thus valid print jobs generated further processing control data 22 preferably comprise default values and corresponding parameter sets for the or each further processing device 12 ,

In the further processing planning module 18 are production possibilities for the or each of the digital printing machine 11 downstream processing device 12 stored or stored, wherein the further processing module 18 one from the digital printing scheduling module 13 provided imposition scheme of a print job with the production capabilities of the or each finishing device 12 and thus verifies whether the imposition scheme using the finishing facility 12 edited and therefore can be handled.

About the postprocessing planning module 18 It is therefore possible, the or each finishing device 12 that a digital press 11 is downstream, automatically integrate into a data flow of a prepress and the printing operation and so automatically the or each finishing device 12 head for. As a result, the entire print job can be handled fully automatically, starting from the pre-press stage to further processing or post-processing, so that printing in the digital printing press 11 and post-processing in the or each finishing device 12 optimally coordinated with each other to further increase the efficiency of digital printing.

At this point it should be noted that it is the digital printing press 11 and every digital press 11 downstream processing device 12 can deal with assemblies from different manufacturers.

Furthermore, it is possible in the further processing planning module 18 incomplete parameter sets for the or each further processing device 12 to complete automatically and to optimize corresponding parameter sets.

The processor 23 can status messages of the individual finishing devices 12 to the further processing planning module 18 to transmit, for example, in the case of an error message a finishing device 12 a limited availability of the respective further processing device 12 during the automatic examination of the respective imposition by the further processing planning module 18 automatically take into account.

As 1 can be removed, exchange the printing press computer 16 and the finishing computer 23 sync data 25 from, namely synchronization data 25 for speed synchronization and section synchronization.

Speed synchronization will change the printing speed of the digital press 11 on the further processing speed of the or each further processing device 12 Voted. As a result, a constant web tension for the printing material web to be printed can then be ensured.

Section sync enables both forward sync and backward sync.

For forward synchronization, the digital press is used 11 as a clock for the or each finishing device 12 , whereas in the reverse synchronization, a further processing device 12 as the clock for the digital press 11 serves.

With the production planning and production control system according to the invention 10 can therefore be the or each of a digital press 11 downstream processing device 12 be controlled automatically. In doing so, not only the printability of a print job on the digital press is automatically determined in advance 11 but also the processability of an imposition scheme of the print job on the or each further processing device 12 checked.

Only if both the print job on the digital press 11 is printable as well as the respective imposition scheme on the or each finishing device 12 can be processed automatically, the printing of the print job is allowed. In all other cases, the print job is deferred until the validity or validity of the print job regarding printability on the digital press 11 and with regard to processability on the or each further processing device 12 is made.

The core component of the production planning and production control system according to the invention is the further processing planning module 18 which automatically generates a generated imposition scheme on its processability on the or each finishing device 12 checked.
