Preparation for Dye sublimation printing

During the process of digital sublimation printing, we should prepare the following things we need in advance:
1. an inkjet printer having Sublimation inks
2. sublimation paper
3. heat press machines 
4. Substrates (the surface on which image is to be transferred),such as T-shirt, cloth, tiles, metal boards, mugs, plates,etc

Sublimation transfers are made from special sublimation dyes that penetrate synthetic materials like polyester when you apply heat and pressure. During the transfer process, the dye heats up and turns into a gas that bonds with the synthetic portion of the fabric. No other decorating process can beat sublimation for the brilliance of color and durability. Because the sublimation process dyes the fibers of a garment, instead of putting a layer of ink on top of the fabric, the image cannot crack, peel, or wear off. The trade-off with using the sublimation process is that for the chemistry to work, it must be used with shirts that have a high polyester content (at least 50%).
Sublimation paper used is a specially coated paper which does not absorb the ink and thus helps in transferring maximum ink onto the surface of the substrates.
Note:The more polyester in the shirt, the better the quality of the image.
