Latest Patents

One of Walter Trachslin's latest patents involves a security element designed for the authentication of a substrate. This innovative security element features a pattern comprising optical diffraction elements that are embossed in a plastic carrier material, along with unembossed neutral areas. On the embossing side of the carrier material, a reflecting layer is applied only to the surfaces with relief structures of the diffraction elements. The neutral areas, which lie between these structures, remain free of the reflecting layer, making them non-reflecting. When this security element is applied in the form of a stamp onto a substrate, and if the carrier material is transparent, image portions covered by the stamp can be discerned through the neutral areas.
