Dye Sublimation is the method of applying an image to specially coated ceramics, metals and polyester cloth, using sublimation ink, heat and pressure.
Sublimation ink has the ability to convert from a solid to a gas without going through a liquid form. The conversion is initiated by heat and controlled with pressure and time. Hard items such as ceramic, fiber board, metals, etc. requires a special coating to accept the sublimation inks.
