摘要： In order to achieve a larger color gamut, more colorants are used than the classical three chromatic colors cyan, magenta and yellow. The use of extra process colors, such as red or orange, green and blue, poses extra requirements on the screening process or on the color separation process. A method is described in which optimal color rendering is achieved by use of maximum three chromatic colorants at the same place only. In one embodiment particular sets of three chromatic colorants each cover color sub-gamuts which are disjunctive, allowing each input color to be located within one color sub-gamut. A set comprises no complementary colors.

摘要： A profile editing system enables modifications to source/destination color data and/or gamut maps. Generally, there are three process flows for color profile editing according to the invention. A first type or type-A process is directed to a method for gamut mapping source color data to destination color data. The method comprises modifying the source color data in a source color space, based upon a color profile edit. This generates modified source color data. Then, the modified source color data is converted to the destination color space to produce the destination color data. Type-B processes are directed to methods for gamut mapping source color data to destination color data and then modifying the destination color data, based upon a color profile edit to generate modified destination color data. Finally, or type-C processes are directed color profile edit that are applied directly to the gamut map that converts the source color data to the target color space to thereby produce the destination color data.
摘要翻译：配置文件编辑系统能够修改源/目的色彩数据和/或色域图。通常，根据本发明的颜色轮廓编辑有三个处理流程。第一类型或类型A过程涉及用于将源颜色数据色域映射到目的地颜色数据的方法。该方法包括基于颜色配置文件编辑来修改源颜色空间中的源颜色数据。这会生成修改的源颜色数据。然后，将修改的源颜色数据转换为目的地颜色空间以产生目的地颜色数据。类型B处理涉及用于将源颜色数据到目标颜色数据的色域映射的方法，然后基于颜色配置文件编辑来修改目的地颜色数据以生成修改的目的地颜色数据。最后，或者C型处理是定向的颜色简档编辑，其直接应用于将源颜色数据转换为目标颜色空间从而产生目标颜色数据的色域图。
