Color embossing

from Wikipedia, the free encyclopedia

In book production or in general paper or cardboard processing, color embossing (also embossing foil printing or hot foil stamping ) refers to the embossing of an element (text or logo) in a material, with a thin foil provided with a layer of color running between the embossing stamp and the material ( embossing foil ). The color is transferred to the material to be embossed by the action of heat and pressure from the embossing stamp. Typical applications of color embossing are the design of author names, publisher names or book titles on the book spine or the front cover of the book, as well as the design of lettering on high-quality packaging.

The die consists of metal (usually magnesium or brass alloys) in order to be able to transmit the necessary forces during the embossing.

Underneath the material to be embossed is a counter die ( patrix ), which either flat is (then there is only a transfer of the color instead) or a negative of the stamper is (then the subject is additionally as a relief in the material embossed ).

Friedensreich Hundertwasser and other artists use this technique to provide their screen prints and etchings with metal foil surfaces.
