“…Three records at 570, 695 and 830 nm have been chosen in the article (Fig 5). At the blockage of 570 nm there is no more yellow component [11], the recording at 695 nm does not have information about magenta. Hidden text Z appears at these blockages because there is a lack of one (Y) that is, two dyes (Y, M) in its environment.…”

Near infrared Z values are determined with spectroscopy of colorants, which are used in security charts, printing of documents and banknotes. A new application of security methods in informatics is being observed in this article. The processes of dyeing of fabrics are being controlled by programming twin dyes. Two different mixtures of dyes have been created for the same color. They differ in light absorption only in NIR area. The given, desired difference in their values of light absorption and NIR spectrum has been achieved. Conversely, those are two dyes of different mixture but with the same color parameters in the visual spectrum. The dyes have identical spectra graphs of light absorption in the visual area. The experimental result has been shown in the gallery with infrared pictures and through the design of textile clothes that carries the hidden information. The design with text-IJNTR-VZ security‖ has been analyzed by forensic light blockages from 400 up to 1000 nm. Index terms-Twin colors and dyes, invisible information, NIR spectrum, security graphics, INFRAREDESIGN.

“…New twin colors are achieved in a few steps. The first step of recipe dyes is calculated with the mathematical relations published in Technical Gazette [12]. The second step is to print the twins, measure the ΔE and perform spectrography to correct the quantities of process dyes, because the print is made by digital printing on canvas.…”

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.

“…This is also a test for the use of unrestricted, continuous palette of colors for digital print on cardboard according to the method of VZ separation. The design of the drug packaging was photographed with a forensic camera [9] Projektina, model PAG 50. Twenty-two photographs were produced after printing.…”

The dual VIS/NIR method is a new process in printing. This paper will attempt to broaden the application and research of new methods of marking cardboard packaging, as well as improve the protection and sale of products. The information system on packaging is a dynamic one, essentially based on two opposite variables, which creates the need for optimization. Legal norms obligate the producers to state certain information on products, such as information about the harmfulness of smoking or the risk of poison, and visibly display barcodes, which take up most of the space on the box. On the other hand, the graphic, trademark and design elements have to be balanced on the remaining surface of the packaging in order to achieve a clear and recognizable packaging of the product. The textual information is more important for informing the consumer about the product. Symbols on the graphic element of the packaging serve to enhance the memorization, protection and decoration of the product. In this article, the proposal is put forth for expanding the information on the packaging of drugs into the near infrared spectrum. Reading, writing and recognizing such data are performed with infrared cameras which the authors have developed over the past years [1]. A large number of security cameras have been set up in banks, schools, streets, restaurants, shops and private areas [2]. Information with hidden graphics can be found on clothes, ranging from military uniforms to the application in fashion on dresses in the textile industry [3]. The expanded information system with the INFRAREDESIGN® has found its application in the packaging of labels of new products, creating a new marketing system and a new way of informing customers, as well as a new way of protecting products [4], [5]. Hidden images with near infrared technology are expanded not only into the area of design, but also into the area of fine art [6]. The insisting AbstractIn the article is presented the design for security graphics on packaging with invisible information. The color choice is underlined by the INFRAREDESIGN® theory. Individual solutions for joining two independent images are realized with digital printing and interpreted with computer animation. Separation of the dye is performed for the default response of the hidden drawing that is released by the infrared camera. Product recognition is with IRD process as a "visual information identity". Hidden graphics are designed with a protective line solution. Experiments have been carried out in the pharmaceutical field, on the packaging of drugs. Proving the authenticity of the content is carried out by recording the packaging and comparing it with the specimen that was recorded as photographs of the twenty light blockades in the visual and infrared spectrum.
