Hot stamping is a printing process that uses heat and pressure to transfer a metallic or colored foil onto a surface, typically paper, plastic, or leather. This technique creates a shiny, embossed effect, making it popular for adding decorative elements to products like packaging, labels, and business cards. The process involves a stamping die that is heated and pressed against the foil and substrate. The heat activates the adhesive on the foil, allowing it to bond to the surface. Hot stamping is valued for its durability and the high-quality finish it provides, enhancing the visual appeal of various items.
