“…[6,7] The authors propose the dual design of an image that automatically identifies pedestrians using dual cameras that are installed on the road. With these dual cameras, it is possible to detect and distinguish individuals wearing marked clothing that is not visually noticeable or salient, while they have individualized markings in the hidden NIR spectrum [8]. With the inclusion of parallel, simultaneous observation in two light regions, the topic of detecting, tracking, and searching for an individual or group expands.…”

In this paper, we publish the algorithm to create a dual image manifested in the infrared and visible spectrum. To distinguish the information in the two light spectra, twin dyes are introduced for the inkjet plotter and printing realization for garment and canvas items. The graphics, invisible to the naked eye, are designed for the near infrared (NIR) spectrum and are suitable for urban security where surveillance cameras with IR detectors are installed. The duality of dyes is presented in tables, and the analysis is a basis for programming and developing new algorithms for the application of “Infrared Dyeing” on different materials and printing technologies. Through spectroscopy, this innovative solution demonstrates twin colorants by printing in one pass through the plotter such that one image remains visible, while the other one is hidden to the bare eye. The uniform and the school bag cover presented in this paper are kept simple in design because they incorporate information hidden to the naked eye but visible with surveillance cameras and all the other infrared detectors. The article provides mathematical models of duality coloring as a basis for programming the graphic prepress that merges both of the images, the visual one and the infrared one. A topic is the fusion of two images with colors that represent two graphs, with independent contents for the visual and near-infrared spectrum.

“…Although many security cameras use the daytime solar component of the NIR spectrum, this article uses the term "Night Camera" just for the sake of tradition. The introduction of this duality for security cameras enables us to observe NIR radiation in daylight as well as hidden Z image [5]. Clothes today are rich in colors when viewed with the naked eye in daylight.…”

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.
