摘要：Spot dyes join the double feature of the INFRAREDESIGN® theory.A large number of planned colors in graphics of topographic maps,are simulated in the press with only four process colorants.Achieved are seperated infromation for the visible and infrared spectrum.This introduces the protection of printed matter,protection of property,reduces the cost of spot printing of large numbers of layers.For the digital print technology simulation of the merge of “topographical colors” is extended to achieve Infrared graphics.The black color tone,a typical color in cartography,is associated with two dyes with different compositions and different properties in the infrared spectrum.Black twins are programmed for the digital printing form for the printing with CMYK process components,and according to the IRD® procedure.
