| Accurately communicating and reproducing color information have always been being the color management system' s target and an important subject for study among different devices. In order to meeting the needs of the development of opening print system, electronic publishing and network publishing. Several companies formed the International Color Consortium (ICC), and they formulated the relative standards, which have been pushing on the color management system (CMS) and software proofing to develop in the direction of opening and standardization. It is practical and academic to study the characteristics of colorful CRT and the methods of changing color space.In this paper, according to the analysis of ICC standard and characteristics profiles, the CRT is divided into 1331 color square, which is made of 11 grades and is not uniform by using the program C*\ Using Color Monitor Optimizer color square is measured accurately, this paper provides the characteristics of CRT , Such as color space, stability of P, time of uniform, space uniform, channel independent. Using the ICC uniform color space, tone/matrix model and finding table, The models of RGB-CIEXYZ and RGB-CIELAB are founded, which are crossed curve intating, calculating color error, analyzing accurate. Thus the models are improved.The primary attempt and probing are conducted to accelerate the development of the open color man agreement system by the link of CMS and ICC standards, which lays a theoretical base and accumulates the practice experience for the further study in the future. And the developed software has certain applied values in the prepress system. |
