Sublimation is the process of transferring dye to a fabric using very high heat. The images and graphics are printed on special paper and heat transferred to the garment.  The garment remains soft and breathable, even with the ink now being a permanent part of the fabric. Sublimation is great option on light color fabric that is 100% polyester. If the percentage of polyester is lower (ex., 65/35), it will result in a more vintage look.
