Hot stamping, also known as foil stamping or embossing, is a method of permanently applying a colored design, logo, text or image onto a wide variety of objects. Using a heated metal die, color pigments are stamped onto the substrate. The object may also be stamped or embossed without any color. Leather goods are sometimes embossed only.

Although any color can be printed, hot stamping is best known as a method of applying a shiny  metallic gold or silver imprint. Hot stamping works well for most plastics, leather, paper, vinyl, Mylar, wood and specific textiles such as polyester and satin acetate, however metal, ceramic and glass cannot be hot stamped.
