Sažetak
Till appearance of Infraredgraphic® we were occupied only with the visual part of the spectrum, meaning the part people can see. Managing with colors and dyes we widen to first part of near infrared, and the whole range of interest we separate to three parts: visual (400-700 nm, V), spectrum part of transient divarication (700-850 nm) and Z spectrum domain (850-1000 nm). We manage absorption and reflection of light from colorants in the whole region from 400 to 1000 nm with aim of creating new securing graphic system. Visual and and infrared spectrum are carrying individual (separate) graphics, where the second one is observed through appropriate “infrared glasses”. We are introducing new cognitions about colors, investigations and printing praxis with two assortments of dyes that achieve the same response in visual, but different spectral values in infrared spectrum. A new theory in graphic arts science is being established, entitled “dyes and color twins“. Discovery of twins dyes and colors managing, creating twin color twins, is based on CMYKIR separation that has purpose to merge two different, independent images in unique printing form for conventional printing reproduction processes. The document contains multiple information, that each belongs to its own color twin. In the article is presented four color print of a postal stamp in INFRAREDGRAPHIC® technique, twins spectrograms from the same postal stamp, scanning results in several blockage points of V and Z spectrum.
