Germany's O R IS Color Tuner digital proofing system not only has the Color version of the order, the adjustment function more has the special Color school Color function. Color Tuner system based on IC C of the standard Color management Profile scheme, combined with its own tonal whole the characteristics of the adjustment, not only can handle printing Color, and can deal with the special Color image background, and of the image can be different levels in order to adjust the respectively. So in this, use it to illustrate the working principle of color and levels of reducing the order of reducing.
Color Tuner system, good Color reduction function, based on the standard Profile ICC Color management. It use the standard IC C documents, according to the standard model for matching calculations, generating preliminary school's color information. According to the standard color measurement files, after spectrophotometer and corresponding software measurement and operations, get a standard IC C files. IC C file is any digital proofing system of key gravure digital proofing system, need two IC C documents, is a specialized in traditional gravure proofing tear sheets or traditional gravure tear sheets of the IC C file, the other is a digital proofing output equipment for the IC C files. So the standard color measurement file must according to normal gravure process traditional proofing or on a gravure printing and, at the same time, the machine must be digitally proofing output a system made no school color processing of the original sample. They after measuring and after operation got two IC C file can input to the digital sampling system, according to the standard operation mode, are to be automatic matching calculations.
However, in Color Tuner system, also have a perfect level adjustment function curve. Color Tuner system provides C M Y K levels curve adjustment function, can integral control of Color global. For 0% ~ 100% with through the order of different tone area adjustment output devices, and to regulate the amount of ink digital proofing output equipment output C j K Y curve. For example: after IC C preliminary school color, digital and traditional gravure compared the sample, the sample is slightly yellow, so still, can reduce Y curve by output value of the corresponding areas, to put the whole yellow effect to correct it.
Of course, in Color Tuner system, also selective school Color function. This is digital proofing color reduction in a ring of very professional. The so-called selective school color, is in the designated color hue area, according to the operator set yourself role tolerance on the basic color value, or contrary to the adjustment of the color concrete numerical value. For example: digital tear sheets of 50 M Y 50 of the effect of the same sample relative to traditional color is concerned, slightly yellow, and two tickets in the sample 3% ~ 97% of color are close to the gradual change effect. If only the adjustment function curve is not likely to take Y 50 M of 50 color shift correction good. Care Y 50 M, then yellow gradient is 50, attend to the latter, not so, Y 50 M 50 of the color shift will not solve problems. At this time, we should use selective school color function, which can realize the tonal reduction plan of both worlds.
Color Tuner system support various print output devices, such as Epson, H P, C anon, etc. Epson inkjet printers to, for example, adopting micro piezoelectric principle produce C M Y K, LM and LC 6 color ink drops, controlling the size, and can generate of different size large drops and small drops, the main role in the image were dark and bright color, it is in the area of the order reduction very favorable.
Because technology also with the gravure proofing gravure printing development, especially in the digital realm now gravure pulls the development, produce larger development space. Because of their own grinds proofing technology technical characteristics and now the technology and equipment of the improved, making the application of the gravure pulls more convenient, also make the gravure printing the technology now or in the future regardless of the printing industry, will be a pivotal status.
