Abstract:
The invention relates to a method for printing a nanostructure and/or microstructure (5) on a substrate (1) having a three-dimensional macro-surface (6). The method is characterized in that a substance (12, 13) is applied having a three-dimensional stamp macro-surface (10), the shape of which matches the macro-surface (2) of the substrate (1) at least in some sections and which is provided with a stamp nanostructure and/or microstructure (10), and the stamp (4) is positioned relative to a substrate (1), and the stamp (4) and substrate (1) are brought together, thus printing the substance (12, 13) as a nanostructure and/or microstructure (5) onto the substrate (1). The invention further relates to a stamp (4) for carrying out the method, and to a substrate (1) produced with said method.
