My Designs? Sublime. The Paper? Sublimation Perfection.
Size: 8.5"X11"
Prints clear, presses clean, and never lets me down—unless I’m the problem (which is often). I keep this stocked like toilet paper. You don’t want to run out mid-project.

Great Quality
Size: 8.5"X11"
This A-SUB sublimation paper is a great quality. I have been using it for many years and have had absolutely no issues. I use it with an Epson 2780 inkjet printer. I have never had a jamming issue or smudging.

Happy to find a seller that carries the 120
Size: 8.5"X11"
I’ve been doing sublimation since May 2025. I have tried a variety between 105, 120 and 125. I’m not exactly sure why 120 ASub it is becoming harder to find . I absolutely love it. When I make my stainless steel tumblers, my colors pop more with 120.

Great Sublimation Paper – Perfect for Mugs
Size: 8.5"X11"
I purchased A-SUB Sublimation Paper 8.5x11 Inch 120GSM and I’m very happy with the results. The colors transfer beautifully. I used it for sublimation mugs and the print came out vibrant, sharp, and very professional-looking. No fading, no dull colors. I also tried using it for a cap, but the issue was not the paper — my cap heat press machine didn’t perform well and the transfer failed. For mugs, this paper works perfectly. Highly recommend for mug sublimation projects.
