Printing technology: Dye-sublimation printing is a digital printing technology using full color artwork that works with polyester and polymer-coated substrates. Also referred to as digital sublimation, the process is commonly used for decorating apparel, signs and banners, as well as novelty items such as cell phone covers, plaques, coffee mugs, and other items with sublimation-friendly surfaces. 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. In sublimation printing, unique sublimation dyes are transferred to sheets of sublimation paper via liquid gel ink through a piezoelectric print head. The ink is deposited on these high-release sublimation transfer paper, which are used for the next step of the sublimation printing process. After the digital design is printed onto dye sublimation paper , it is placed on a heat press along with the ...
