Simulation of spot colorants for cartographic printing in the visual and infrared security CMYKIR system

Set is a system of security colorants for copyright protection in the cartographic press. Five colorants and two black colorant twins are used for protection in the print of topographic information. Z black marks constructed buildings and area names. V black marks roads and paths. The black colorants of the Z system has positive Z values at 1000 nm. The Z value of V black is zero. The rest of the colors are in the V system without any response in the infrared spectrum. Set is a double reproductive state of the given mathematical model for the EuroStandard color settings for offset printing on cartographic paper. The settings are suitable for the management in two spectrums: visual and infrared. Proposed is the change of the composition of spot dyes from the system of colorants set for the cartographic print. Introduced is the prepress with the simulation from CMY colorants and two different black dyes with the value of Z max, Z = 0 in the infrared spectrum. Scanning such IC maps printed with the simulation method with process dyes reveals the forgery that was not originally produced with this procedure. The copyright of the map producer is protected through digital information in two spectrums.
