Paper Abstract

This white paper reviews the method for making bearer printed information indistinguishable on a non-copyable substrate when a copied attempt is made on either an analog or digital electrostatic photocopier device. In 1995 we received patent number 5,704,651 for a non-copyable technology trademarked MetallicSafe. In this patent the abstract describes the usage of a reflective layer, formed on a complex pattern region and having graphic or font size shapes and type coordinating to particular patterns in the complex pattern region. The technology used in this patent has now been improved and evolved to new methods of creating a non-copyable substrate trademarked CopySafe+. CopySafe+ is formed of a metallic specular light reflector, a white camouflaged diffused light reflector, and the content information 'light absorption' layer. The synthesizing of these layers on a substrate creates dynamic camouflaged interference patterns and the phenomena of image chaos on a copy. In short, the orientation of a plurality of spectral and diffused light reflection camouflaged layers, mixed and coordinated with light absorption printed information, inhibits the copying device from reproducing the printed content.
