My Go-To Sublimation Paper — Flawless Results Every Time
Size: 8.5"x11", Size: 8.5"x11"
This is hands down the best sublimation paper I’ve used and the only one I continue to buy. I get a perfect transfer every single time—no fracturing, no fading, and no uneven results. The paper dries fast, which makes my workflow so much smoother, especially when I’m producing items in batches.
I use this regularly to make air fresheners and tote bags for my small business, and the color payoff is always vibrant and crisp. The transfer rate is excellent, and it works beautifully on light-colored, high-quality polyester and other sublimation-ready surfaces.
If you’re a small business owner or crafter who values consistency, quality, and ease of use, this paper is absolutely worth it. I highly recommend it and will continue to repurchase.

Best Sublimation Paper
Size: 8.5"x11"
I’ve been using A-Sub paper for my sublimation projects, and it is easily one of the best. The ink dries almost instantly once printed, so I don’t have to worry about smudging the design or getting those annoying "pizza wheel" marks from the printer rollers. The paper itself feels substantial and doesn't tear or curl easily. One of the biggest wins for me is that it never jams; it feeds through perfectly every time, saving me the frustration of wasting expensive ink and paper.
When I go to press my designs, the ink releases almost completely, leaving very little behind on the paper and putting all that color onto the project. The final results look super professional, with colors that are vibrant and sharp rather than looking faded or dull. It has worked perfectly for everything I’ve tried so far, and if you want a reliable paper that gives you consistent, high-quality results, this is definitely the one to get.
