When a print project needs an elegant, non-tarnishing metallic finish to be applied to paper or a similar substrate, it's easily accomplished using a process referred to as foil stamping or hot stamping.
The reproduction of graphics such as logos, polished metal, or highlighted spot areas requiring a high quality reflective image can be effectively achieved by using foil films rather than metallic inks for the end result.
Metallic inks, which are similar to standard printing inks, provide a subdued metallic appearance. The natural tendency of the ink to be absorbed into the stock contributes to a duller looking effect.
Foil stamping or hot stamping (as it is called when heat is applied) requires a metal plate with an engraved image. The plate strikes a foil film, transferring the foil coating from the roll film onto the substrate that is to be imprinted.
The substrate then receives the high-density metallic finish, resulting in a reflective image with a bright and dense metallic appearance. A wide selection of foil colors, finishes, and effects are available such as gold, silver, and colored metallics; marble, leather, wood, snakeskin, and pearl finishes; and geometric multi-dimensional patterns.
