What type of paint base is needed to sublimate on?

To sublimate effectively, you need a paint base that is polyester or has a high polyester content. This is because sublimation works by turning solid dye into gas without passing through a liquid state, which bonds best with polyester fibers. Materials specifically coated for sublimation printing, such as polymer-coated substrates, are also suitable. Avoid using natural fibers like cotton, as they do not hold the dye well during the sublimation process.
