Case study carbon black separation extended features

Case study in work is determining extended black separation in current graphic arts, in infra red properties. Graphic reproduction is generally based on screening system, principles of subtractive synthesis and separation with mostly added black, with infrared Z absorption. Subtractive ternary color combinations could be partially substituted with black, that can lead to achromatic way of reproduction, with various extended possibilities. The aim is to prove stability of achromatic system, and operating in NIR domain, as wide acceptance is desirable.
