本文件定义了一组墨水值组合数据，可用于描述四色印刷工艺。该数据集未针对任何印刷工艺或应用领域进行优化，但对于所有一般应用而言都足够强大。虽然它主要用于用CMYK油墨进行彩色印刷，但也可用于三种彩色油墨和深色油墨的任何组合。 本文件是ISO？12642？2数据集的替代品，其中需要更多中性刻度数据。它不是作为ISO？12642-2的替代品设计的。

This document defines a data set of ink value combinations that can be used to characterize four-colour process printing. This data set is not optimized for any printing process or application area but is robust enough for all general applications. While it is primarily aimed at process colour printing with CMYK inks, it can also be used with any combination of three chromatic inks and a dark ink. This document is an alternative to the ISO？12642？2 data set where more neutral scale data are desired. It is not designed as a replacement for ISO？12642-2.
