This paper explores the relationship between additive and subtractive mixing for colour printing. Using Spectraval mica pigments (Merck)—marketed as RGB pigments—colour is generated by selective reflection and prints are based on additive colour mixing principles, that when printed onto black paper, create white and a range of colours. Although currently used mostly for decorative effects, they can be the basis of additive 'process' inks, that present new opportunities for and challenges to traditional print markets. The viewing angle dependency of their selective reflection favours applications in security printing similar to the holograms on bank cards for example. Traditional measurement and modelling methods are difficult to apply due to the layering and irregular dispersion of pigments.

本文探讨了彩色印刷中加色和减色混合之间的关系。使用Spectraval云母颜料(Merck)(作为RGB颜料出售),颜色是通过选择性反射产生的,并且打印是基于加色混色原理的,当打印到黑纸上时,会产生白色和多种颜色。尽管目前主要用于装饰效果,但它们可以作为添加剂“工艺”油墨的基础,为传统印刷市场带来新的机遇和挑战。它们选择性反射的视角依赖性有利于在安全打印中的应用,例如类似于银行卡上的全息图。由于颜料的分层和不规则分散,传统的测量和建模方法很难应用。
