Full dye sublimation heat transfer is a process for transferring designs onto fabrics and other materials using special inks and heat. The process begins by printing a design onto sublimation transfer paper using sublimation inks. The inks are specially formulated to turn into a gas when heated, allowing them to penetrate the fibers of the fabric. The transfer paper with the printed design is then placed on top of the fabric and heat and pressure are applied. The heat causes the inks to turn into a gas and penetrate the fibers of the fabric, creating a permanent, high-quality image on the fabric.
