Sublimation is the process of transferring dye to a fabric using heat. The image is printed on special paper placed on the garment and heat is applied, allowing the ink to become part of the fabric. This will leave you with a more breathable, soft-hand feel to the fabric. The best part is that the numbers, letters and graphics do not wear off! Sublimation is a great process that allows for vibrant, full color, all-over prints.
