Abstract
A method for producing a surface structure for a metallic press plate, endless belt or a cylindrical embossing roller through at least one laser and a device for using the method. In order to provide a cost effective production for the surface structure while using environmentally friendly techniques, it is proposed to use a laser which produces the entire surface structure through partial removal of a surface of a metallic press plate, endless belt or embossing roller to be processed. Thus, the laser is controlled by a provided 3D topography, wherein control of the laser is performed through obtained x, y and z coordinates in order to produce a depth structure, so that high portions and low portions are formed.
