Sublimation uses a process where the ink becomes part of the fabric rather than adding a layer on top. This results in a transfer that is unmatched in both durability and feel. On the other hand, heat transfer paper adds a layer on top of the garment.
Also question is, can I print sublimation paper on regular printer?
You can use a standard inkjet or laser printer to print onto this paper with your normal inks. You then place the paper onto your clothing and use a heat press, or in some cases, you can use an iron, and peel away the paper. Your design will then be stuck-on to your garment, and you will be able to see the transfer.
