本文研究多色印刷过程中的色品范围。七色调（7色）打印-多色打印的最有前途的变种-提供了一个显着更大的色域比传统的CMYK打印过程，接近CRT和电影色域。在设备无关的CIE-XYZ和CIE-L*u*v* 色度空间的过程中的行为进行了探讨，使用为此目的开发的复合纽介堡模型。提出了一种简单直接的无莫尔条纹分离方法。所提出的分离过程的优点是，对于包括黑色在内的任何奇数个基本颜色，只需要3个不同的屏幕层。
The present paper studies the chromaticity gamut of multi-color printing processes. Heptatone (7-color) printing - the most promising variant of multi-color printing - offers a significantly larger gamut than a conventional CMYK printing process, approaching CRT and film gamuts. The behavior of the process in the device-independent CIE-XYZ and CIE-L*u*v* colorimetric spaces is explored using the compound Neugebauer model developed for this purpose. A simple and straightforward Moire-free separation process is proposed. The strong point of the proposed separation process is the fact that only 3 different screen layers are needed for any odd number of basic colors including black.
