Infrared design on textiles as product protection

This paper is on the method, theoretical basis and application of textile protection based on the use of the infrared light area for controlling printing dyes and textile dyes. The innovation has the goal to use planned coloring in order to determine a product's authenticity by using a wide range of wavelengths from 400 nm to 1000 nm. The goal is selected appearance of graphics, separately in daylight, and separately in the infrared spectrum. Each color hue is joined with characteristics that may have two different states. The first state is when the target color is observed in daylight only, and the second state is when that same color is detected under infrared light. Double separation is introduced with CMYK printing dyes that controls the appearance of infrared (IR) effect or blocks it. The name of this method is CMYKIR. Up to date such designs have been demonstrated in graphic product security systems, in documents, books, posters, packaging material. Extending application to textiles is a natural path of applying security graphics and this can provide good quality and improvement of checking a product/brand authenticity. Pokazujemo rezultate takove primjene preko otisaka na svili i platnu. The contribution contained in this paper is the method of modeling a color graphic with controlled appearance of its parts in the infrared area. The method is extended to the possibility of planning double visibility with colors that are embedded into the very material that is to carry its own infrared protection.
