Dye sublimation transfer paper A4 Size is a specialized type of dual size coated paper that is used in dye sublimation printing. In this process, the paper is printed with a special dye ink that is designed to bond with polyester or other synthetic materials.

The printed image is then transferred onto the substrate (usually fabric) using heat and pressure, causing the dye to sublimate or turn into a gas, which then penetrates the fibers of the substrate and permanently bonds with them.

Dye sublimation paper is specially coated to accept the dye ink and release it during the transfer process. It is available in a variety of sizes and weights, and the choice of paper depends on the type of substrate and the specific requirements of the printing job.

It is important to note that dye sublimation printing is not suitable for printing on natural fabrics such as cotton, as the dye cannot bond with the natural fibers.
