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 5 microns thick, KolourOptik products seamlessly integrate into banknotes and other government documents without the need for specialized equipment or processes.
