Sažetak
The INFRAREDESIGN® is introduced into the fabric dyeing technology in order to give a new dimension to security cameras in urban areas. The visible pattern of colors also contains a carefully designed hidden image. The hidden image is detected instrumentally in the infrared area. The arrangement of pigments on the fabric is determined using computer graphics by programming dual, "twin" colorants. Recipes for ink components consisting of colorants cyan, magenta, yellow and black are proposed in this article. The inks differ in monochromatic photography in the near-infrared spectrum. The clothes have two images, two independent pieces of information. One is intended for the visible spectrum and can be seen with the naked eye in daylight. The other image is separated (detected) with a camera which "sees" the intended infrared graphics. Cameras in the streets of our cities observe the environment during the day and night. Through the lens of the "night camera", the interested observer discovers messages designed on his or her favorite brand. The clothes are given new value in the eyes of the observer; the brand is elevated to a new level of "dual communication". Security print is a combination of vector and pixel graphics which manifests itself in the visible and near-infrared spectrum.
