Thermal screen is heat sensitive material to which your design is 'burned' to when thermal screen printing.

Thermal screen is made from a durable polyester mesh backed with a plastic film. While passing through the thermal screen maker (thermal imager) the plastic backing melts away, resulting in a stencil being created. (No need for solvents, knives, or photography.) After printing with water-based inks, the framed screen can be cleaned easily with water, then dried and stored for future use.

When used with water-based inks, these 70-mesh screens can produce several hundred prints; enamel and plastisol inks can be used for smaller runs. A standard thermal imager (3M or Panenka) can image the 70-mesh screen sheets.
