Ready to press sublimation transfer. Sublimation Transfers: The sublimation transfer must be used on a 65% or more polyester garment. 65% polyester will give it a vintage look. To get the most vibrant look, use 100% polyester. The garment must be used on a light colored fabric. The transfer will not print white. The colors on the listing may be slightly different from the transfer. You will need a heat press for using this transfer. Instructions will be included with the transfers.
