Security Features Deliver Movement, 3D Depth, and Multiple Colours
Exclusive to the government and banknote security industry, KolourDepth™ is easy to initiate and intuitive to authenticate. Based on KolourOptik® nano-optic display technology, KolourDepth security foils and stripes deliver movement, 3D depth, and multiple colours in a wide array of custom design options that capture and hold the user’s attention as they inspect and authenticate a banknote or government document. KolourDepth security foils and stripes are nearly impossible to reproduce or reverse engineer due to Our proprietary software algorithms and patented nanostructures, microstructures, and nano-fabrication techniques. KolourDepth® is exceptionally thin (< 5 micron) and suitable for multiple application processes and substrates.
