Foil stamping

Adapted from Wikipedia: http://en.wikipedia.org/wiki/Foil_stamping

Foil stamping, typically a commercial print process, is the application of pigment or metallic foil, a special film-backed material, to paper where a heated die is stamped onto the foil, making it adhere to the surface leaving the design of the die on the paper. Foil stamping can be combined with embossing to create a more striking 3D image.
