What is Sublimation Transfer? Sublimation is the process of combining heat and pressure to convert ink on special sublimation paper to gas(without converting it to liquid), and then impart the impression depicted on the paper onto the end product. In the simplest terms - heat+pressure+ink on sublimation paper -> transfers the image on the paper to ceramic metal or other treated surface.
The end product receiving the image can be something that contains polyester, such as a T-shirt (the more polyester, the deeper the impression), or it might be metal or ceramic, such as a mug, and be coated with a special polymer coating that allows the design to permanently adhere to the final product.
