Quick answer: Good sublimation paper needs a fast-drying coating that releases ink cleanly under heat and holds sharp detail without bleeding. Cheap, uncoated, or generic inkjet paper will smear, under-transfer color, or curl in the heat press, so it's one of the few supplies not worth cutting corners on.
What Makes Sublimation Paper Different from Regular Paper
Sublimation paper has a special coating that temporarily holds the printed dye on the surface until heat and pressure release it into the polyester or polymer coating on the blank. Regular inkjet or copy paper doesn't have this coating, so the ink either soaks in and won't transfer, or transfers unevenly with poor color.
What to Look For
Fast-release coatings (paper that lets go of ink quickly under heat, reducing "ghosting" or double images from shifting during pressing), consistent weight, and a size matched to your printer and blanks. Most letter- and legal-size sheets made for desktop printers fall roughly in the 100-125 gsm range; lighter papers (often 70-100 gsm) are more common on rolls for wide-format printers. A-SUB sublimation paper is a popular, reliable choice for small shops running letter-size desktop printers.
Common Paper Mistakes
Printing on the wrong side (sublimation paper is one-sided; printing on the coated side is what makes the transfer work), storing paper somewhere humid (it absorbs moisture and prints unevenly), and using paper that's too lightweight for large, saturated designs. If you're seeing faded or streaky transfers even with good paper, check our sublimation printer maintenance guide, since ink issues are often mistaken for paper issues.
Where to Buy
DTG PRO's sublimation supplies section carries paper alongside compatible ink and blanks, which is convenient if you'd rather buy everything from one source and know it's designed to work together. If you run a converted Epson EcoTank that uses 502, 512 or 522 bottles, Castle Ink stocks a compatible sublimation ink 4-pack to pair with your paper. As of November 2026, expect to pay roughly $15-$30 per 100 letter-size sheets of a reputable brand; our sublimation cost breakdown shows how paper fits into your per-item cost.
Which Side of Sublimation Paper Do You Print On?
Print on the bright white, coated side. The back is usually slightly duller or off-white, and many brands print a logo or pattern on the back to make it obvious.
If you can't tell, lightly wet a fingertip and touch a corner on each side; the coated side usually feels slightly tacky. Load paper so the printer prints on that side, which on most Epson EcoTanks means coated side facing you in the rear tray.
What Paper Weight Is Best for Mugs vs. Shirts?
A heavier sheet in the roughly 120-125 gsm range is a good default for mugs, tumblers, and heavy-coverage designs, because it holds more ink without cockling. Lighter sheets work well for small apparel designs and press flatter on fabric.
Whatever you choose, keep one paper for your production work and build your color settings around it. Switching brands often shifts colors enough to need a new ICC profile.
Is Tacky Sublimation Paper Worth It?
For polyester apparel and stretchy fabrics, yes. Tacky paper grips the garment when heated, which prevents the shifting that causes ghosting, especially on all-over prints and when you open the press.
For mugs, tumblers, and other hard blanks, standard paper secured with heat-resistant tape is usually enough, and it costs less.
Does Sublimation Paper Go Bad?
It doesn't expire quickly, but it does absorb moisture. Paper stored in a humid room can print blotchy and transfer with uneven color.
Keep opened packs sealed in their original bag or a zip-top bag, away from humidity and heat. If you suspect damp paper, a few seconds under the heat press (hovering, not clamped) before printing can drive out moisture.

Frequently Asked Questions
Can I use regular printer paper for sublimation?
No. Regular paper lacks the release coating, so most of the ink stays in the paper and the transfer comes out faint and blurry.
Do I need to mirror my design on sublimation paper?
Yes, for most blanks. The print faces the blank during pressing, so text and asymmetric designs must be mirrored. Our guide on how to print a mirror image covers the settings.
Does sublimation paper work in any printer?
Only in a printer filled with sublimation ink. The paper itself feeds like normal paper, but regular ink won't sublimate into the blank.
Why does my sublimation print look dull on the paper?
That's normal. Sublimation colors look muted on paper and only become bright after heat pressing onto a polyester or coated blank.
Can you reuse sublimation paper?
Not for a second full-color transfer. Most of the ink is released during the first press, so a reused sheet gives a faint, uneven image.
