Excellent Sublimation Paper – Perfect Prints Every Time!
Size: 8.5"*11", Color: 150 sheets
This sublimation paper is fantastic! It’s high-quality and works perfectly with my sublimation printer. The prints come out vibrant, sharp, and transfer beautifully onto mugs, shirts, and other materials without smudging or fading.
The paper is easy to handle, doesn’t jam in the printer, and holds the ink well for a clean transfer. I’ve tried other brands before, but this one consistently gives professional-looking results. Definitely a must-have for anyone doing sublimation printing!

This paper prints beautifully!
Size: 8.5"*11", Color: 150 sheets
Great sublimation paper. I usually use A Sub but ordered this because it delivered faster, and now this is the paper I’ll be using! It prints wonderfully! The ink release is amazing! There’s hardly any ink left in the paper and my shirts look incredible. The paper is a great weight and doesn’t jam at all. If you’ve been disappointed with your sub print quality, give this paper a try. You won’t be disappointed!
