Hot stamping, also known as foil stamping or heat embossing, is a printing process that uses a heated die to transfer foil (metallic, pigmented, or holographic) onto a surface like paper, plastic, or leather, creating a shiny, elegant, or tactile effect for branding and decoration. It combines heat and pressure to bond the foil to the material, producing high-quality, durable designs, often used in luxury packaging, bookbinding, and automotive parts.
