Hot Foil Stamping is a printing technique that applies metallic or pigmented foil to a surface, creating a shiny and eye-catching effect. This process involves using heat and pressure to transfer the foil onto materials like paper, cardboard, or leather. It is commonly used for adding decorative elements to items such as business cards, invitations, and packaging. The technique begins with a metal die that has the desired design engraved on it. When heated, the die presses the foil onto the substrate, adhering it in the shape of the design. This method is popular in the printing industry for its ability to produce high-quality, vibrant finishes.
