ICC Color Management how to make up for lost colors

icc color management, there are other ways is CMM (color management modules Microsoft), another is CMM (color matching method) plus a color engine (Adobe), there is also a CMS (color management system) system, like Apple's colorsync or Kodak's, and this PCs profile connection (ICC specifications) is the space for color conversion, Or RCS reference color space (Adobe)

icc terminology, input profile (color space to PCs), output profile (PCs to color space) and display (display), device link, color space, abstract, named color (i.e. Pantone, HKS), color space mode can be CMYK, grayscale, RGB, lab/xyz. Device link refers to the action of connecting two ICC or three ICC. One is input print. Output is the word that the staff must check the different structures and parts of the fatigue testing machine. These two ICC can be connected together, which has special adsorption function and other characteristics. The two ICC are connected together by the color engine of a CMS software, so today we assume that the color produced by RIP is inaccurate, You can use device link, which can be combined into three. For example, the Japanese color is imported today, but the printed copy is to be sent to the United States, so when you get this copy, you need to print a standard like the United States. The input is Japanese color, the simulation object is swop, and the output is a printer. In this way, you can combine three. There is also the use of poor paper to make a better color gamut, so that the color gamut is reduced step by step, so the level of this kind of printing is much better than converting the large color gamut directly to the level of small color gamut, so the color gamut conversion is of course a technical problem

icc basics is already very good, but it seems that there is still room for improvement, because some data will be lost during gamut compression. Can we find a way to lose the least, that is, workflow makes color correspondence table. The computing space of ICC is actually a 3x3 matrix, from gamma RGB to white point to PCs XYZ. Can we do more matrices to make the color more accurate. In addition, CMM will have different results in different profiles (RGB, CMYK, grayscale, lab). Another method is workflow. The input of reference is based on the data of lab. you can go to proof when making a cone. After proof, you can do measurement. After measurement, you can do comparison. After comparison, you can do proof. After proof, you can go to measurement and then compare. Therefore, you can make the color points of each color block very accurate, and the error can really be less than 1. Such a workflow TBALE method, If you keep giving back, you can make the color more accurate

dot proofing is the same principle, that is, to change the size of the input point is to change the measured lab data. The relative engine converts it. After the point size is changed, it is also to match the lab data. Because when dot is expanded, it can also be simulated during dot. Generally speaking, dot-294 environmental vibration must be simulated by dot gain, because the whole color will be accurate when dot gain is simulated

creates a perfect balance between stiffness and toughness
