Abstract
A method of producing a deforming tool (2) having a structured embossing surface (4) which can be brought into contact with a surface of a substrate (1) for plastic deformation thereof (of the substrate), the method comprising: determining a target structure to be produced on the substrate (1); geometrically distorting the target structure, such that an “embossing image structure” is obtained; inverting the “embossing image structure”, such that the embossing structure for the embossed surface (4) is obtained; and producing the embossing surface (4) of the deforming tool (2) according to the embossing structure.

A method of producing a deforming tool (2) having a structured embossing surface (4) which can be brought into contact with a surface of a substrate (1) for plastic deformation thereof (of the substrate), the method comprising:
- determining a target structure to be produced on the substrate (1);
- geometrically distorting the target structure, such that an “embossing image structure” is obtained;
- inverting the “embossing image structure”, such that the embossing structure for the embossed surface (4) is obtained;
- and
- producing the embossing surface (4) of the deforming tool (2) according to the embossing structure.
A deforming tool (2) having a structured embossing surface (4) which can be brought into contact with a surface of a substrate (1) for plastic deformation thereof wherein the deforming tool (2) is characterized in that the deforming tool (2) has a working roll (3) a surface of which bears the embossing surface (4), and in that a structure of the embossing surface (4) has a plurality of elliptically shaped patterns which have their main axes oriented transversely to a rolling direction.
