Background technology
The newspaper printing of prior art, usually adopt the quality control bar, it is to adopt pin point technique, the site, be produced on the film and a kind of instrument that forms with lines etc. on the spot, be to implement a kind of means that the printing quality datumization is measured and controlled, be used to observe and evaluate the printing quality of color right printed matter, managing for printing process control and printing quality provides objective standard.Its major function is in order to estimate the color rendering and the tone reproduction of printed matter, also can monitor chromatography precision, ghost image, printing down exposure, forme resolution etc.The quality control bar claims printing signal bar, printing control strip again.A. the quality control bar can be divided into three major types by the class of its information that can provide: 1. signal strips is made up of several blocks, range estimation or just can find out quality problems with general magnifier.For example the expansion of site with dwindle, axial or circumferential ghost image, three look chromatography grey balances, the exposure during printing down what, the resolution of forme etc.2. test-strips is made up of some test cells, not only has the function of signal strips, can also carry out Measurement and analysis by specialized instrument and equipment.Such as measuring colour density etc. with the beam split chromascope.3. the function of signal testing bars bar and test-strips haves both at the same time.B. can be divided into by its function and form: 1. color is controlled 2. contrasts and is controlled 3. chromatographys and control the usually multiple function one of collection of 4. printing down exposures, 5. plate resolution quality control bars, based on one, two kind of function, and names with correlation function.
According to the ratio juris that loses lustre, reach neutral grey process by three primary colors Huang, product, blue or green chromatography, be called gray balance, that is grey balance.Theoretically, with three primary colors equivalent stack chromatography, should obtain neutral ash, just can think that at this moment tone is well reproduced, color obtains correct control.
Grey balance is all very sensitive for various very little fluctuation, often can demonstrate quite little difference, if colour cast will appear in three primary colors out of trim a little.In press, 1% variation takes place in each monochromatic site tone pitch, just can find out the variation of tone from the grey balance piece.From physiology, people's vision refers to that eyes are very responsive for grey balance, and just according to these characteristics, people are with the instrument of grey balance piece as the control color.
In actual applications, the double exposure three primary colors of equivalent can not obtain neutral gray, but grey shows brown slightly, thus when setting trichromatic ratio, should suitably improve blue or green ratio, thus keep grey balance.Trichromatic ratio can also should be done some adjustment according to actual production conditions with reference to related standards.
Now existing specialized vendor provides the quality control bar, the precision height, and function is complete, and is very worthy.The domestic Brunale control strip of using morely that Switzerland is arranged, the GATF asterisk of U.S. printing fund association, the FOGRA printing control strip of Germany, the PS version printing down step-wedge of Japanese fuji etc.
But, how designing the ash balancing signal strip of passing judgment on the printing quality of newspaper by visual observations at low cost, prior art does not have ready-made solution.

Embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in each accompanying drawing.
The newspaper of band ash balancing signal strip of the present utility model is printed with ash balancing signal strip at the centre joint or the afterbody of newspaper, and this ash balancing signal strip comprises that four color lumps and three cut apart vitta.
In ash balancing signal strip embodiment one shown in Figure 1, color lump 1 is the black of K30%, and color lump 2 is neutral ash, color lump 3 is the black of K30%, and color lump 4 is neutral ash, and vitta 5 is the cyan of C50%, vitta 6 is the magenta of M50%, and vitta 7 is the yellow of Y100%.
In ash balancing signal strip embodiment two shown in Figure 2, color lump 1 is the black of the neutral ash of going up of level boundary, following K15%, color lump 2 is the black of the neutral ash of going up of level boundary, following K30%, color lump 3 is the black of the neutral ash of going up of level boundary, following K50%, color lump 4 is the black of the neutral ash of going up of level boundary, following K30%, vitta 5 is the cyan of C50%, and vitta 6 is the magenta of M50%, and vitta 7 is the yellow of Y100%.
In ash balancing signal strip embodiment three shown in Figure 3, color lump 1 is the black of going up neutral ash, following K15% that becomes 60 ° of angle oblique lines boundary with level, color lump 2 is the black of going up neutral ash, following K30% that becomes 60 ° of angle oblique lines boundary with level, color lump 3 is the black of going up neutral ash, following K50% that becomes 60 ° of angle oblique lines boundary with level, color lump 4 is the black of going up neutral ash, following K30% that becomes 60 ° of angle oblique lines boundary with level, vitta 5 is the cyan of C50%, vitta 6 is the magenta of M50%, and vitta 7 is the yellow of Y100%.
In Fig. 1 to Fig. 3, described color parameter is a usefulness of distinguishing ash, black block and monitoring network amplification degree for printing process, sideline in the synoptic diagram and ash, the decomposition line between black, become oblique line separatrix, 60 ° of angles 8 with level shown in horizontal separatrix 8 as shown in Figure 2, Fig. 3, reality does not exist, ideal state is greyish black one integrated mass, has not both had to overlap the double line that produces, and does not also have and separates the blank bar that forms.
Ideal state is that a row control strip same wide with black road is set, and is placing grey balance lines that traverse the space of a whole page, about 2 millimeters of width aspect the telegram end Mo Lu.According to the technology/equipment situation, can locally monitor the printer's ink road in actual applications, local standard is provided, binding operation personnel's experience accomplishes the end in view.
Because the position of ash balancing signal strip is that setting is constant, if big advertisement has occupied the position of control strip, this version has not just had control strip.Sometimes advertisement needs layout, though war does not occupy location advertising, gives the leeway of signal strips very little, if the stick signal bar will increase layout than big workload, easily produces the error of piecing together registering, also unsuitable at this moment stick signal bar.Adopt Computer To Plate to be expected to solve these problems that advertisement causes.
Use ash balancing signal strip to bring about tangible results, specifically comprise:
1. provide black amount color standard, stabilized product quality.
2. before fast judging in-problem seal, the printing reason.
3. convenience, effective instrument are provided, have reduced to start to print and report setup time, won seal and report the vital timeliness of enterprise.
4. reduce and start to print newspaper and open and expend, reduce cost.
5. reduced the operation easier of printed color advertisement and important picture, the combination of adjusting production factors (board, personnel) to the workshop brings convenience, and has strengthened adaptability to changes.
6. the judgement for quality dispute provides simple and clear, a straightaway diagnostic criteria.
The function of ash balancing signal strip and form design:
1. the grey balance piece is made different sites and become the grey block of number, so that compare at low-key, middle tone and lofty tone.Because middle tone is main keynote, we consider to show with the color lump of two different one-tenth numbers.Referring to Fig. 2 and signal strips shown in Figure 3.
Can judge the form and aspect correctness by range estimation grey balance piece, thus the control tone, correct reproducing colors.
2. grey block is as the main body of signal strips, and it is bigger for good than black block to make it area.Ash, the black area of embodiment two type signal strips as shown in Figure 2 are than 2: 1.At the correspondence position of grey block, put the mesh of corresponding one-tenth number and transfer black block.
Take this to compare the consistance of ash, black block density.Also can roughly understand or measure the situation of black dot gain rate by magnifier and instrument.
3. green grass or young crops, product, yellow elongate strip color lump are set, and the site becomes number to be respectively C50%, M50%, Y100%.
Can roughly understand or measure the situation of 50% blue or green version and red version dot gain rate by magnifier and instrument.Because yellow do not develop the color, be difficult to determine site one-tenth number, so yellow elongate strip is made Y100% with method intuitively.Grey balance yellow ink amount can be controlled indirectly by grey balance.
4. the size of signal strips is set relevant with the unthreaded hole aperture of the detecting instrument of enterprise use.Consider that from being convenient to detect the minimum dimension of signal strips should be slightly larger than the unthreaded hole aperture at least.
5. under the desirable chromatography situation, both do not had the separatrix between the grey black dichromatism, do not had the gap yet.During register trouble, lines or blank gap will be between the grey black color lump, overlapped, the color code of register trouble color can be judged from the color of lines.
Between the Huang product cyan piece and adjacent grey black color lump of signal strips, from designing the elongate strip blank at shape inclination angle at 45, see illustrated in figures 1 and 2, yellow product lividity appearance is overprint error laterally or longitudinally, the capital changes elongate strip, and one adjacent of two elongate strip broaden, and one narrows down, and form contrast.Be easy to find out the overprint error of two aspects in length and breadth in view of the above.
Register trouble also can make the grey black color lump of embodiment two types, embodiment three type signal strips directly become broken line at hypotenuse.
5. on design, adopt line, face combination, form the inclination angle, deep or light variation is arranged on color, be lively in form, have aesthetic feeling, unshowy again.Both paid attention to practicality, noted pro forma attractive in appearance again.
Designing and producing of signal strips is principle according to grey balance, utilizes computer software to finish designing and producing of signal strips, and the e-file of made signal strips is set in each format allocation really once, directly calls format during the group version and gets final product.
The sort signal bar is made simple, and is easy to use, the degree of accuracy height, and no foozle, no cost of manufacture, never wornout, the signal strips method for making of a kind of simple and feasible of can yet be regarded as.
Use drawing software, according to corresponding data design drawing is made accurate signal bar figure as CoreIDRAW, the operable e-file of formation group version be placed on each pre-set format once really on the allocation, but this format repeated multiple times is called.Can on the direction of black road, place three or more signal strips by left, center, right.Split newspaper and can be placed on the telegram end position, if this version have telegram end then to place about two, four open newspaper is placed on side or centre joint place.Figure four splits space of a whole page newspaper for the band ash balancing signal strip, from left to right, be arranged with 6 signal strips, its type is respectively: ash balancing signal strip embodiment three types, ash balancing signal strip embodiment two types, ash balancing signal strip embodiment one type, ash balancing signal strip embodiment three types, ash balancing signal strip embodiment two types, ash balancing signal strip embodiment one type.
Figure five from top to bottom, is arranged with 3 signal strips for four of the band ash balancing signal strip face newspaper of starting an edition, and its type is respectively: ash balancing signal strip embodiment three types, ash balancing signal strip embodiment two types, ash balancing signal strip embodiment one type.
The most preferred embodiment of the above is intended to specify thinking of the present utility model: signal strips is designed to comprise four color lumps that are arranged in order, the color-set of each color lump becomes neutral gray and/or black, and wherein the color composition of at least two color lumps comprises neutral gray.The enforcement of the utility model is not limited to the disclosed mode of above most preferred embodiment, and is all based on above-mentioned mentality of designing, simply deduces and replace, and the newspaper of the concrete band ash balancing signal strip that obtains all belongs to enforcement of the present utility model.
