The content of the article is the expansion of INFRAREDESIGN® technology in achieving a hidden image in the scope of fashion clothing. Recognition and selection of two pictures are being demonstrated by a double camera for the visual and infrared spectrum, as a film record set up to a web space, and as reproduction printing on canvas. The portrait is placed in the computer graphic, and their reproduction has been realized with cyan, magenta, yellow and black dyes. The portrait invisible to the naked eye is at the same time a security graphics, hidden information, individualized sign and a new way of branding textile products. The result of dualism of different dyes with C, M, Y, K components is a system of twins of identical dyes in the visual spectrum and with different light absorption properties in the near infrared spectrum. The experimental scope or dye spectroscopy is from 400 to 1000 nm.
