Abstract

Verfahren zur Bearbeitung einer metallischen Oerfläche. Die Oberfläche wird zur Bildung einer Prägeoberfläche zunächst mit einer Tiefengrobstruktur versehen. Danach wird die Oberfläche in einer ersten Bestrahlungsstufe durch Bestrahlen mit Partikeln oder durch Ätzen oder dergleichen mit einer Tiefenfeinstruktur mit einer ersten Rauhtiefe versehen. Danach wird die mit der Tiefenfeinstruktur mit der ersten Rauhtiefe versehene Oberfläche im Bereich der Täler der Tiefengrobstruktur mit einer Schutzschicht versehen, wonach die aus der Schutzschicht herausragenden Höhen der Tiefengrobstruktur durch Bestrahlen mit Partikeln oder Ätzen oder dergleichen mit einer Tiefenfeinstruktur mit einer zweiten Rauhtiefe versehen und schließlich die Schutzschicht entfernt wird. Mit einer nach diesem Verfahren bearbeiteten Prägeoberfläche lassen sich unterschiedliche Effekte im Aussehen einer geprägten Folie erzielen. Handelt es sich bei der Tiefengrobstruktur um die Abformung einer Oberfläche natürlichen Leders, so läßt sich dessen Aussehen in hohem Maße nachahmen, wenn die Rauhtiefe der Prägeoberfläche im Bereich der Höhen größer ist als im Bereich der Tiefen, was dann beim geprägten Produkt umgekehrt der Fall ist. Die Höhen sind dann glänzender als die Tiefen, was dem Aussehen natürlichen Leders entspricht.

Process for processing a metallic surface. To form an embossed surface, the surface is first provided with a deep coarse structure. The surface is then provided with a deep fine structure with a first roughness depth in a first irradiation stage by irradiation with particles or by etching or the like. Thereafter, the surface provided with the deep fine structure with the first roughness depth is provided with a protective layer in the valleys of the deep coarse structure, after which the heights of the deep coarse structure protruding from the protective layer are provided with a second fine roughness depth by irradiation with particles or etching or the like and finally the protective layer is removed. With an embossed surface processed according to this method, different effects in the appearance of an embossed film can be achieved. If the deep coarse structure is an impression of a surface of natural leather, its appearance can be mimicked to a great extent if the roughness of the embossed surface is greater in the area of the heights than in the area of the depths, which is the reverse for the embossed product , The highs are then shinier than the lows, which corresponds to the look of natural leather.
