A METHOD AND A DEVICE IN EMBOSSING, AND A HOT FOIL STAMPING PRESS

摘要

A method and a device for producing a diffractive microstructured area on the surface layer of a substrate by embossing. The device comprises a hot foil stamping press (10) comprising a press member (1) and a backing member (5), and in which the press member (1) and/or the backing member (5) is provided with at least one embossing pattern corresponding to said microstructured area (4), against which the substrate (3) is pressed during the embossing, when said substrate is introduced between said press member and said backing member for the embossing. A method for converting a hot foil stamping press to an embossing device for producing a diffractive microstructured area on the surface layer of a substrate by embossing, wherein the press member (1) and/or the backing member (5) of the hot foil stamping press (10) is fitted with at least one embossing pattern corresponding to said microstructured area (6) for embossing.
