Note: as Epson printers are not specialist sublimation printers, you should not use the ink that comes with the printer. I have found that the best sublimation paper for Epson 2720 is A-Sub paper, which is very highly regarded in the sublimation community. You also need high quality sublimation paper for the best results. You can use a fabric that is a cotton / polyester blend, up to 30% cotton, but the colors will be duller, with less vibrancy.
Remember that this transference works best on pure polyester. In order to complete your sublimation printing, you would then need a heat press to transfer the design to your fabric. The sublimation printer fulfills step 2 in the above list.
