Sublimation printing is a digital printing process that involves transferring a design onto a special transfer paper using sublimation ink. The transfer paper is then placed onto the final product, typically a polyester or polymer-coated item, and subjected to high heat and pressure, which causes the ink to sublimate or become a gas. The gas then penetrates the surface of the product, resulting in a permanent, full-color print. Sublimation printing is ideal for producing vibrant, high-quality prints on items such as t-shirts and more. It is also popular for its ability to produce photo-quality images with sharp, detailed lines and colors.
