The dye-sublimation printing process is used to print on polyester or other synthetic fabrics. It is used for applications such as T-shirts, banners, table covers, ID cards, sportswear and flags. The dye sublimation inks are a pigment suspended in liquid solvent, like water (sustainable printing). The images are initially printed on coated heat-resistant transfer paper as a reverse image of the final design, which is then transferred onto polyester fabric in a heat press operating at a temperature around 180 to 210 C (375 F). Under high temperature and pressure, the dye turns into gas and permeates the fabric and then solidifies into its fibers.
