Device for Fine Embossing of Packaging Material With a Set of Embossing Rolls of the Male/Female Embossing Type

摘要

The embossing device for fine embossing of packaging material has a set of embossing rolls with female embossing and male embossing rolls, in each case the structural elements (ML1) of the female embossing roll (M1) and the structural elements (PL1) of the male embossing rolls (P1) being assigned to each other, and the structural elements of one of the rolls being produced independently of the structural elements of the other rolls. At least one structural element (ML1; PL1) of at least one roll (M1, P1) is provided on its bottom surface (B1) and/or surface (S1) and/or side surfaces and/or in its immediate surroundings with light-scattering elements (DM1, D1), the height (H) of which is 10 μm to 150 μm. As a result of the use of light-scattering elements with small dimensions, the contrast of the structural elements can be increased substantially, by which means the overall aesthetic image is improved considerably.
