Sublimation blanks have a polymer coating (or high-polyester surface) that permanently accepts sublimation dye — press a printed design and it becomes part of the surface, photo-quality and unpeelable.
Can I use sublimation blanks without a sublimation printer?
The coating specifically needs sublimation ink and heat. Without that setup, decorate standard blanks with UV DTF transfers instead — full-color results, zero printer.
