ISO 12642-2:2006定义了用于描述四色印刷工艺的油墨值组合数据集。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。考虑了使用胶印、凹印、柔版印刷和其他印刷工艺进行出版、商业和包装印刷的需求。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。它是ISO 12642-1数据集的替代品，需要更可靠的数据。

ISO 12642-2:2006 defines a data set of ink value combinations that is intended to 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. The needs of publication, commercial, and package printing with offset, gravure, flexography, and other printing processes have been considered. While it is primarily aimed at process colour printing with CMYK inks, it can also be used with any combination of three chromatic coloured inks and a dark ink. It is an alternate to the ISO 12642-1 data set where more robust data is required.
