Hot Press

A heat press is a machine engineered to imprint a design or graphic on a substrate, such as a t-shirt, with the application of heat and pressure for a preset period of time. While heat presses are often used to apply designs to fabrics, they can also be used to imprint designs on mugs, plates, jigsaw puzzles, and other products.

The pattern is printed in sublimating ink on sublimating paper which allows the pattern to transfer. You can get some highly effective patterns and great effects using this technique.
