Dye Sublimation, as a process is really very simple. It is the method of applying an image to specially coated ceramics, metals and polyester cloth, using three main ingredients: sublimation ink, heat and pressure. Sublimation ink is unique in its ability to convert from a solid to a gas without going through a liquid form. (Just like dry ice). The conversion is initiated by intense heat and controlled by pressure and time. As the inks change from solid to gas an endothermic reaction takes place and the gassed inks permanently affix to the sublimation product.
