Research On The CMS Of Digital Proof

How to make the proof simulate the printing actually is always an important subject for people to research. In this paper, being with the application of the CMS, An new CMS mode of digital proof was put forward according to the new color management system WCS, which was the color management mode based on the CIECAM02 color appearance model. The color management for proof was achieved.In this paper, the author analyzed the current saturation of the Color Management System and the development course of the Color Appearance Model, and done the detailed research on the elements and characteristic of the CIECAM02 color appearance model, so the CIECAM02 was used as PCS to do color convert of XYZ for printer and printing press based on WCS. Then the color gamut contrast graphic was sketched using the software of MATLAB. Because of the gamut of printer is bigger than the printing press, in order to solve the disaccord of color gamut in the course of converting of the color information among different devices, the segment maxima method for calculating gamut boundary descriptors is used to describe the color gamut boundary of printing press in CEECAM02 color appearance space, present an algorithm combining space analytic geometry to realize the gamut mapping, and has been achieved the gamut mapping from printer to the printing press. In the end, this paper adopts the estimate method of the chromatic aberration to estimate the whole color management system based on the CIELAB color space, and analyzed the reason of the appearance of the error.The adopted of the Color Appearance Model is a necessary uptrend. This paper achieved the CMS mode based on CIECAM02 as PCS, it has great value to the further research on the Color Management System of Digital Proof.
