Dye Sublimation Transfer is a process where you take an image that has been created digitally (either by scanning, downloaded from a digital camera or created on your computer). The image can then be printed with a printer using special sublimation transfer inks onto transfer paper. When heated to high temperatures, sublimation ink turns into a gas. Pores of the polymer coated item open up and allow the gas to enter. Then, once removed from the heat, the pores of the polymer substrate close up, trapping the ink inside. The entire image will be smooth to the touch. This is a transfer process in which the image becomes a part of the actual item. Sublimation needs special ink, paper and specific substrates with polymer coating to work.
