Sažetak
Dual images printed on fabric are achieved due to INFRAREDESIGN®, through twin colors basic. Tentative part is performed on cotton fabric through CMYKIR technology principles of separation and matching of colors. Sophisticated barrier scanning while procreating testing model, is performed for ultraviolet, visible and near infrared part of the spectrum. This method leads to moving boundary scope of security printing and dual information to a variety of possible printing substrates and sheltered information to materials like silk, cotton, leather, polyester and similar by appliance of twin colors and dual information. These diversity of possible substrates, variations in dyes mixture combinations and coverages allows technologist and designers wide field of concepts, projects and acquirements. IRD technology is based on developing and forming “twin dyes”, whose spectral characteristics for this appliance, some here are presented. Also some additional tools for better visual twins matching are introduced. All observed twins render same spectral characteristics designated as Z domain, beneath 900 nm area with ∆Z difference for “visual and NIR” dyes.
