High Transfer, Bright Colors & No Ghosting
Size: 8.5"*14", Color: 150 sheets, Size: 8.5"*14", Color: 150 sheets
This HTVRONT sublimation paper 8.5x14 inch has been excellent for my sublimation projects. The 120gsm weight feels sturdy and feeds smoothly through my inkjet printer without jams or curling. It holds ink well, which helps produce clean, sharp prints before pressing. The transfer results are impressive. Colors come out vibrant and true, with strong detail and no dull or faded areas. I’ve had very little ghosting, and designs transfer evenly onto shirts, mugs, and other sublimation blanks. The claimed high transfer rate really shows in the final results. I also like the larger 8.5x14 size, which gives extra space for bigger designs or multiple smaller prints on one sheet. The paper releases well during pressing, leaving minimal residue and clean edges. Pros: ✔ Bright, vibrant color transfer ✔ Minimal ghosting or smudging ✔ Smooth printer feeding ✔ Great for shirts, mugs, and hard blanks ✔ Good value for the sheet count Cons: – Must be used with sublimation ink – Requires correct heat press settings for best results Overall, this HTVRONT sublimation paper is a reliable choice for anyone doing sublimation printing who wants strong color transfer, crisp detail, and consistent results. Great for both beginners and small business use.

Thin but with extra step works great
Size: 8.5"*11", Color: 150 sheets
It sublimated great but it’s thinner than what I normally use so it take an extra step to not have over lapping but it’s cheaper and you get more so definitely worth the price

Great product, quality colors and vibrant prints
Color: 1BK/1C/1Y/1M
Best Sublimation Ink I have found so far. Great size bottles for the price you pay. Lasts a long time and the colors print great and when you press the print the colors come out BEAUTIFUL and VIBRANT! Dries quickly after printing so no worries on smudging but even after sitting over a month on the paper still presses like you printed it that day!

I’ve been consistently purchasing this Hiipoo sublimation ink for my sublimation printers, and I’ve been extremely pleased with the results. The print quality is excellent, with vibrant colors and clean transfers every time. What I really appreciate is how true the final product turns out compared to my original designs. The colors stay accurate, and the finished results look exactly the way I intended, which is very important for my projects and products. This ink has been reliable and consistent, and I will definitely continue using it for my sublimation work.
