Epson EcoTank ET-2800 can be used ONLY for printing transferable designs onto sublimation paper.
Sublimation is a type of printing in which the ink when heated to a certain temperature will heat into becoming a gas that embeds itself into the surface of an object. This technique is typically used to place images or designs on polyester or polyester coated items such as tumblers, mugs, pens, hats, and more.
Note: Make sure any of your prints for sublimating are in the correct orientation for your project before printing as when the design is transferred onto the object it usually needs to be mirrored.
