Convex gilding
Raised metallic foil. This technique is the matrix-free application of metallised film. Using very strong pressure rollers, it is applied over the entire surface. The metallised foil only adheres to the convex special material giving a beautiful effect of a thick convex layer of gold, silver or another colour.
