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.

Abstract:We present extended visual and infrared colour management with the application in packaging print in this paper. Visual design is a vector graph which is masked by pixel graph according to a plan which altogether allows visibility of packaged product. The hidden information, invisible to the naked eye, is printed on the transparent foil and is identified by an infrared camera. Two independent pieces of pictural information are made with the "dualcolours". Each tone of colour consists of two different process components which respond differently in near infrared spectrum. Duality of graphic design for visual (V) and near infrared (Z) spectrum is designed for the print with process colours. The recipes for dual colorants are achieved by near infrared spectroscopy. A new mathematical regression model is provided for transparent material which is applied in food packaging. The infrared vector graphics increases safety quality of packaging technology; against copying, scanning and subsequent reproduction.

The focus of this paper is the introduction of new security elements into the authenticity of information on documents which concern the traceability of products. This article proposes dual marking using the infrared printing technology, which involves differences between the visible and infrared spectrum and separate detection of certain information with an infrared camera. Each meat product is assigned a unique designation, embedded in the document and hidden from the naked eye, in order to prevent changing, scanning or modifying with currently known techniques. A product receives a certificate with a security approval which carries information about the complete traceability of the product. A new central data registry which collects information from all necessary sources is proposed. The web portal and the accompanying database are designed to work in the cloud. The security of the exchange of data between the server and the user is ensured. The information about the traceability and the delineation between the visible and infrared hidden are approved and coordinated by the relevant authorities, breeders, distributors and sellers. The design of the entire information presents completely transparent information about the products to the end consumer.

Safety graphics on drug packaging are presented using infrared colorants according to the recipe for VZ twins for offset printing. The mathematical model of the individual shape of raster (screen) elements, "the FourHorns" (FH), is presented here along with the performance solution in PostScript. Safety procedures have been expanded with linear typography print, but by using low resolution screens on the border of recognition. The design was applied in the print on drug packaging subject to different weather conditions which affect and change the color tone of V and Z twins during longer time periods. The visual design (V) is shown and transformed into near infrared spectrum (Z) using the method of digital animation. The presentation is based on the methods of creating animated movies by combining eight photographs which were made using a forensic camera with light filters for the range from 400 to 1000 nanometers. The visual and near infrared absorption of sunlight is shown in continuity, including the Z1 and Z2 area of wavelengths.
