Sublimation is a process by which sublimation dyes are printed onto a transfer medium (sublimation paper) with a specially prepared inkjet printer. Thereafter, those dyes are then transferred from the sublimation paper to a garment under the heat and pressure delivered by a commercial heat press. Sublimation only works on garments made from 100% polyester or with a polyester face. When the heat and pressure are applied, the dye on the transfer medium sublimates, or becomes a gas, and is then absorbed into the polyester itself; the print is actually a part of the garment/coating and doesn’t add any texture or weight.
