标准范围

本文件规定了一个程序,包括计算,用于将ISO 18619:2015中描述的方法扩展到n色ICC配置文件,特别适用于xCLR情况,其中着色剂为CMYK plus组合,来自红色、橙色、绿色、蓝色和紫色,或者,对于3CLR情况,着色剂为具有大间距色调角的类似CMY的着色剂。15076-1中允许的其他颜色空间类型,如2CLR(两种设备着色剂),本文件不涉及。

This document specifies a procedure, including computation, for extending the method described in ISO 18619:2015 to n-colour ICC profiles specifically for the xCLR cases where the colourants are either CMYK plus combinations from the set of red, orange, green, blue and violet or where, for the 3CLR case, the colourants are CMY-like chromatic colourants with widely-spaced hue angles. Other types of colour spaces which are otherwise permitted by 15076-1, such as 2CLR (two-device colourants), are not addressed by this document.
