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 of the substrate, includes the steps of 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 is brought into contact with a surface of a substrate (1) for plastic deformation of the substrate, the method comprising:
- determining a target structure to be produced on the substrate (1);
- geometrically transforming the target structure along at least one main direction along which the substrate is deformed during the plastic deformation, such that an embossing image structure is obtained;
- inverting the obtained embossing image structure, such that an embossing structure for the structured embossing surface (4) is obtained;
- and
- producing the deforming tool (2) having the structured embossing surface (4) comprising the obtained embossing structure.
