Abstract: Research on MCCM includes the formulation of printing color standards of applied color chart，Screen reproduction of color standards and printing restoration，expert system of color design and etc. Through the crucial techniques and technical difficulties，the paper depends on the principle of chromatics and experimental analysis to explain exactly the general concept that the range of RGB colors on screen is more than that of printing colors. It not only accounts theoretically for the erroneous phenomena which are produced when printing color standards are reproduced on screen，but also solves the technical problems which longly exist in the research for screen reprodution and printing restoration of printing color standards.

Key words: Printing color standards, Screen reproduction, Printing restoration
