摘要

PPROBLEM TO BE SOLVED: To specify a correspondence relation between RGB data and CMYK data on the basis of only an arithmetic operation or the like based on a complementary color relation. PSOLUTION: When the RGB data are color-converted to CMY data, virtual CMY data are calculated on the basis of the inputted RGB data, the virtual CMY data are color-divided into K data and the RGB data on the basis of a GCR (Gray Component Replacement) technique, and the color-divided K data and RGB data are separated into the CMY data on the basis of the mixing ratio of the CMY data capable of achieving previously-specified designed ideal color reproduction. Thus, the inputted RGB data are color-converted to the CMY data for performing the color reproduction of the inputted RGB data to the designed ideal color. PCOPYRIGHT: (C)2005,JPO&NCIPI

要解决的问题：仅基于基于互补色关系的算术运算等，来指定RGB数据和CMYK数据之间的对应关系。

解决方案：将RGB数据颜色转换为CMY数据时，将根据输入的RGB数据计算虚拟CMY数据，将虚拟CMY数据按颜色分为K数据和RGB数据。 GCR（Gray Component Replacement）技术，并且根据能够实现先前指定的设计理想色彩再现的CMY数据的混合比，将分色的K数据和RGB数据分离为CMY数据。因此，将输入的RGB数据颜色转换为CMY数据，以执行将输入的RGB数据颜色再现为设计的理想颜色。
