Polyester color dyes are printed onto sublimation paper using a photo quality electronic printer, the dry dye is then transferred to the garment. There is no film layer applied to the garment, the process literally dyes the polyester fabric so you can’t even feel the print. Sublimation transfers are a relatively quick and easy way to put a photo or other complex images on polyester garments or other polyester substrates. As with clear transfer films it is used for white or light colored garments. The garment color will be seen in the design and affect the colors. Dark garments are not suitable. Image detail and wash-ability are excellent.
