INDENTIFICATIEKAART, EN EEN WERKWIJZE OM DEZE TE VERVAARDIGEN. |
摘要 |
A hallmark for example for a solid plastic identification card consisting of a plurality of layers is described. The hallmark is formed by means of only partially overlapping color coatings on a monochromatic or monochromatically printed substrate foil. More plastic foils are laminated onto the substrate foil, if desired. Single-layer printed portions of the surface appear bright in transmitted light and dark in incident light; multi-layer printed portions of the surface appear dark in transmitted light and bright in incident light, thus producing a watermark-like effect. |
