Patent ID: 7690300

Claim:
A method for producing an object comprising: producing steel intaglio structures in an original printing plate; producing at least one gap in the surface of the original printing plate having the steel intaglio structures; producing an embossing die with embossing microstructures, wherein at least one of at least one of a height and a lateral structural size of the embossing microstructures is of an order of magnitude in the range of 5 to 100 microns, and at least one of a height and a lateral structural size of the embossing microstructures is of an order of magnitude of less than 1 micron such that a diffractive relief structure can be embossed therein; and inserting the embossing die into the gap such that the those parts of the embossing microstructures closest to the surface of the original printing plate are located 20 microns to 100 microns below said surface, wherein a plurality of matrices are embossed from the original printing plate with the embossing die inserted into the gap, said matrices being disposed side by side and connected to constitute a mold.
