KolourOptik®: Nano-optic Display Technology for Government Document Authentication and Banknote Security
KolourOptik® is a patented technology providing government document and currency authentication. It combines sub-wavelength nanostructures and microstructures to create modern overt security features with a unique and customizable visual effect. KolourOptik pure plasmonic colour pixels patterned on ultra-thin microstructures create the thinnest full colour 3D movement security stripes and threads that are nearly impossible to replicate. KolourOptik originations are developed in a Class 100 cleanroom environment using the world’s most sophisticated electron beam lithography and proprietary nano-fabrication techniques to create the most uncompromising overt and covert banknote security and document authentication solutions in the market. At less than 10 microns thick, KolourOptik products seamlessly integrate into banknotes and other government documents without the need for specialized equipment or processes. KolourOptik was a finalist for the International Association of Currency Affairs (IACA) 2020 Excellence in Currency Technical Awards in the category of ‘Best New Currency Innovation’.
