Platen
The heated upper surface and the cushioned lower surface of a heat press, between which the garment and transfer are compressed.
Definition
The platen is the flat surface of a heat press between which the garment and transfer are sandwiched during the press cycle. The upper platen is heated and applies controlled temperature to the transfer side. The lower platen is rubber-coated and provides even back pressure during the dwell time. Platen size dictates the maximum design size that can be pressed in a single cycle. Common apparel platens are 15 by 15 inches or 16 by 20 inches. Cap and mug presses use curved platens shaped to match the substrate. Worn or uneven platens cause inconsistent pressure and edge lift defects.
