Foil stamping is a specialized printing process that involves the use of heat, pressure and metal foils to create shining metal like designs, texts, and graphics in a wide range of colors and textures.

It is also called hot stamping or hot foil stamping since the process is largely dependent on the heat for transferring the images from the hot stamp on a chosen surface.

“Dry stamping”  or “dry foil stamping” is another name given to foil stamping. This is because the technique does not involve the use of any kind of liquid ink for the purpose of printing. Instead, dies and carved metallic plates are used for the stamping process.

Foil Stamping involves the use of a specialised multi-layered foil. Typically, the different types of layers in the foil are:

A polyester carrier layer,

A release layer,

Lacquer layers,

Image layers,

Metal layers (gold leaf or gold silver leaf or foil color), and

An outer adhesive layer

During hot foiling, heat and pressure are applied to the foil, which is pressed against the medium supported by a plate or cylinder.

The adhesive layer in the gold foil or silver foil is activated by this heat and pressure, and the release layer melts, attaching the machine hot foil to the medium.

The machine used for this hot foiling process is called a hot foil stamper /hot foil stamping machine. It could either be an independent, stand-alone machine or be connected to a printer or other such equipment.

The dies used in the hot foil stamper are usually made of brass that is etched or engraved manually or through other systems.
