Hot stamping is a technique that grew out of the medieval tradition of book gilding.
We begin by creating a relief engraving, generally in brass, that is a negative image of the pattern or text we wish to create.
This tool is then mounted on a mechanical press that can apply pressure of 2.5 metric tons at temperatures of up to 160°C. This pressure and heat are used to press a sheet of colored aluminum foil or foil of a non-metallic color between the tool and the paper, applying the material to the paper.
A very wide range of metallic and non-metallic colors is available, as well as a variety of effects (matte, diffraction, glossy).
