Sažetak
The procedure of application of Infraredesign ® (IRD) security on the polypropylene transparent food packaging was used in this article. For the given infrared parameter Z=0, 4 an algorithm of creating process twins of polypropylene colors with the same spectral information in the visible part of the spectrum is being defined. The process twins of polypropylene colors created in this way make the base of dual information for the given parameter Z in the NIR (near infra red) spectrum. By regressive analysis of the information on color twins, algorithms for development of a dual color space for the entire visible part of the spectrum are being created. In this way the hidden infrared information, invisible for the eye, are being planned. It is impossible to forge, scan and re-embed such hidden information. Considering the fact that dyes and design must keep their property of transparency, the dyes which are able to achieve a simultaneous duality according to the IRD theory as twin dyes for the visual and infrared spectrum have been chosen.
