As we can see that dye sublimation printing requires heat the act of sublimation occurs when the inks are warmed, turn into a gaseous state, and permeate the substrate. With direct dye-sub, the sublimation process occurs directly on the fabric. With transfer dye-sub, a graphic is first printed onto transfer paper and then infused on the fabric through an external heat source. Although the transfer and direct methods differ, they also share many common benefits.
Sublimation transfer paper is used in textiles and arts or crafts projects. Often, an inkjet or other printer is used to print an image on the paper. Then a heat press can transfer the image onto clothing, canvas, or other surface. Transfer papers now existmostly for textiles, including elastic fabrics used for making sportswear and swimming suits, and for natural fiber fabrics such as cotton, silk, linen, and wool.
In transfer printing, we will use a heat press machine, and adjust the temperature of it can adjust the heat. Too much or too little heat are usually problematic and result in over pressing or under pressing of the substrate. Uneven heating on the press is also an issue and results in spottiness where parts of the substrate sublimate properly but other parts don’t. It is a good idea to invest in temperature strips or a thermal gun, both of which map out the temperature of the heat platen. If there are any inconsistencies or cold spots, it is best to call the manufacturer of the press.
