Dye-sublimation printing technique is quite a relatively new technology and as a process is really simple, only becoming more common place over the last two years. Dye sublimation textile printing is a thermal process whereby colour dyes are transferred from an ink ribbon onto, or rather into, the surface of a special substrate which is then laminated during the final stage of the process.
The dye sublimation printing process is used to print on polyester or other synthetic fabrics.It is used for applications such as T-shirts, banners, table covers, id cards, sportswear and flags.The dye sublimation inks are a pigment suspended in a liquid solvent, like water. The images are initially printed on coated heat-resistant transfer paper as a reverse image of the final design, which is then transferred onto polyester fabric in a heat press operating at a temperature around 180 to 210 C (375 F).
Advantages Of Dye-sublimation Textile Printing:
1. Images are permanent and do not peel or fade.
2. Dye does not build up on the fabric.
3. Colors can be extraordinarily brilliant due to the bonding of the dye to the transparent fibers of the synthetic fabric.
4. Truly continuous tones can be achieved that are equivalent to photographs, without the use special techniques such as half-screen printing.
5. The image can be printed all over the entire item, with no difficulty in printing all the way to the edges.
