Hot stamping is a technique that foils are
multilayered coatings that transfer to the surface of the product. Non-metallic
foils consist of an adherence base, a color layer, and a release layer.
Metallic foils replace the color layer with a layer of chrome or
vacuum-metallized aluminum. Metallic foil construction has a metal-like sheen
and is available in different metal shades such as gold, silver, bronze, and
copper.
Pigment foil does not have a metallic sheen
but may be glossy or matte. Holographic foil paper includes a 3-dimensional
image to provide a distinctive appearance to specific areas of a digitally
printed application.
In a hot stamping machine,
a die is mounted and heated, with the product to be stamped placed beneath it.
A metallized or painted roll-leaf carrier is inserted between the two, and the
die presses down through it.
