Dye-Sublimation Printing is a heat-transfer process, whereby a graphic is printed in reverse on a special transfer paper and heat-transferred while applying high pressure to polyester fabrics. After the paper is printed, the ink/paper is heated to 400+ degrees and using pressure on the paper/ink/fabric, the ink turns into a gas and “sublimates” itself into the fabric – hence the term dye-sublimation. Compared to direct solvent print to fabric, the dye-sublimation process provides more vibrant colors and a photo-clear definition. Another advantage of the dye-sublimation printing process is that these fabric banners are machine washable on a gentle cycle with mild detergent. You can’t do this with solvent-printed fabrics.
