**Sublimation definition:**Sublimation is a chemical process where a solid turns into a gas without going through a liquid stage.
In sublimation printing, we are using a special ink for printing our image on sublimation paper, and then heating up the image to the point where the solid turns into a gas and transfers/bonds to our polyester item. Hence the words "Sublimation Ink." Out of all the methods of printing, sublimation will allow you to heat press the largest variety of items, however, we are limited to MAINLY white substrates.
