The process uses the science of sublimation, in which heat and pressure are applied to a solid, turning it into a gas through an endothermic reaction without passing through the liquid phase. The image is first printed to a special transfer paper. It it then feed through a high pressure roller heat-press which effectively turns the ink in the paper to a gas. The polymer molecules of the polyester or other synthetic fabrics softens under the heat. It “opens up” on a molecular level. The ink which has now turned to gas is transferred INTO the fabric structure which then closes up when combined with the ink.
