Sažetak
Digital print enables control of light absorption in the visual and close InfraRed spectrum by developing a system of dual information. The IRZ method of transformation is being introduced for turning Red Green Blue colours into Cyan, Magenta, Yellow and BlacK dyes with INFRSTRDESIGN method for printers and devices – Computer To Plate – in graphic technology. Consequently, a widened graphic technology based on algorithms and programme solutions for creation of alterative invisible information is being introduced into information science. This paper demonstrates IRD solution which algorithm is contained in printer driver. Since input data include at least two independent pictures, this enables a new steganography method of hiding the information. The second, invisible information can be text, picture or ideogram inserted into the visual information. Term “Z information” is being defined as information/graphic documented on print, invisible by bare eye, available through infrared camera in a close infrared spectrum of 1000 nm.
