Abstract
The apparatus for satin-finishing and embossing flat material comprises a first toothed roller and at least a second toothed roller, with the rollers being disposed in such a way that a tooth each of a roller engages between four teeth of the other roller. One of the rollers comprises at least a microstructure and the other roller is provided at the respective place with a counter-pressure surface. The microstructure is applied to a hard surface layer which is applied via an intermediate layer to the roller surface. The method is especially advantageous if a film with a thermoplastic intermediate layer is used. Such an apparatus allows embossing logos with microstructures at all desired locations of the rollers, thus offering a high amount of security against falsification and a large variety of design features.
