Difference between hot foil and cold foil
Hot foils are opaque sheets that can be printed on paper in any shape or text you indicate in your design. Hot foil is better for text or shapes and minimal designs. This technique is the first choice for many looking for a clean, professional finish. Hot foil can be used in combination with embossing to create a tactile effect that cold foil cannot.
Cold perm is an increasingly popular technique. The technique uses a thin metallic layer on top of the paper with ink printed on the foil. The metallic layer passes through the ink, giving everything a glossy and reflective quality. The main benefit of cold foil is that it can give photographic images a shimmery effect, whereas hot foil is limited to one color. If your design has a variety of gradients, shading, and tinting, we recommend using cold foil.
