With Dye Sublimation (referred to as Dye Sub) the graphics are computer generated and transferred by printing to dye sublimated paper using specialised inks which are then transferred through heat and pressure into the fabric to give you a unique piece of clothing with the image or pattern embedded forever. The image can be all over from seam to seam, will not fade, crack or fall off. Dye Sub can only be done successfully on 100% Polyester fabrics.
