Abstract: A method for generating a structured surface of an embossing tool, in particular a press sheet or a press belt, in order to produce surface-structured panel and/or strip material, in which two or more mutually different partial surfaces are structured in mutually time-separated processing sections. Each processing section involving the following steps in the sequence as follows: masking partial surfaces that are not to be structured in the processing section, as long as they are not already masked, with a cover; removing surface material of the non-masked surface in order to produce a surface structure; optionally removing means used to structure the partial surface; and optionally removing parts of the cover or the entire cover. A pressing tool thus produced can produce imitation wooden panels, the optical effect, which comes significantly closer to the appearance of real wooden panels made with conventional pressing tools.

Abstract: The invention relates to a method for producing etch-resistant structures (masks) on the surfaces of metallic pressing tools, specifically continuous press bands or press plates, by means of a laser, wherein a surface of the press tool to be structured is provided with a thermally sensitive, etch-resistant coating and the laser burns structures out of the etch-resistant coating. In order to prevent negative influences when lasering on the surface of the press plate, the invention proposes that the structure is burned with a laser that emits light having a wavelength in the infrared range between 780 nm and 1 mm.
