What is Dye Sublimation? Dye Sublimation(Dye Sub) is the process where ink is transferred via a paper medium and heat into a polyester garment in full color. Dye Sublimation printing creates images that do not fade over time, do not crack when the garment is stretched and will not wash out. We offer many different garments for Dye Sublimation T-Shirt Printing but the most popular are garments with high polyester content because the print is much more vibrant than on cotton. We can print as little as one Dye Sublimation T-Shirt or Dye Sublimation Mug.
