This is the best luster, the double-sided
Size: 13"x19"
I was disappointed when I accidentally bought the single-sided luster because I like getting double-sided luster from a sub, as it gives you the superior 74 lb paper. I don't even use it to print on both sides. I have it simply because it is thicker, and one thing that I've also noticed that is kind of strange, is this has a better and more textured surface than a Subs single-sided luster for the 13x19 format. I consider the luster that is single-sided, to be a texture that is between what this double-sided Buster is, and A-Sub's Satin finish. Now that I have the premium glossy, the double-sided luster, luster, and satin, I have everything I need for a ton of prints! Thank you so much asub, because you are better quality than the Staples paper which I figured would be the more expensive paper and maybe better because it's coming from a brick-and-mortar store, but your resin Coatings are better than theirs, and therefore yours soaks up the ink faster and doesn't leave Pizza wheel marks. There is simply no reason, unless you have to have the watermarks on the back from the professional paper, to buy professional paper. This stuff is professional just without the water mark or the higher price

Excellent Quality – Perfect for Custom Projects
Size: 13"x19"
When I ordered this paper, I wasn’t sure if it would be thick enough. My daughter wanted to create a custom calendar for the family, and I offered to handle the printing. I noticed it was double-sided and appeared to have a similar finish on both sides, so I decided to give it a try.
To my surprise, the quality was even better than expected. The thickness was just right for the project, and the calendars turned out beautifully—crisp, vibrant, and professional-looking. The paper held the colors well throughout the entire print job.
In the end, the whole family loved how the calendars came out. I’d definitely use this paper again for future creative projects!

A-SUB Iron-On
Number of Items: 20
I am thoroughly impressed with the A-SUB Iron-On Heat Transfer Paper! The color accuracy is excellent; my designs printed vividly and transferred beautifully to my white cotton shirts with pigment ink, looking almost like a professional sublimation print. Printer compatibility is a breeze as it works perfectly with my standard inkjet printer, and I experienced no paper jams.
For use, it's incredibly versatile for DIY projects like t-shirts, tote bags, and aprons. The included instructions were clear, making the transfer process with my home iron straightforward for a beginner like me. The paper's thickness feels sturdy enough to go through the printer without issues but isn't overly bulky on the fabric after pressing.
Considering the quality and the number of sheets in the pack (I got 20 sheets for around $14 USD), the value for money is fantastic. The transfers have held up well after several washes (following the care instructions carefully—inside out, cold water, no bleach), with no cracking or peeling. This is a great product for anyone looking to personalize their wardrobe!

Looking for JetProSS? This is the closest you will find on Amazon, might even be better?
If you are like us and have been in need of JPSS quickly, i'm sure you have tried various brands on here that were available for white the next day. Some come close to Neenah's almost perfect Jet Pro line but you typically get the 'negative' area dark box on lighter greys and even on some whites.
Since we are familiar with A-Sub's amazing Sub paper, we deceided to give this a run for the money.
Impressive. This paper is awesome! Really like the outcome of the graphic. Were just a few of the comments made by pressers that day.
Think we are going to give a head-to-head competition with some this week and will post pics post-press and after washing to see how it holds up vs JPSS
Stay away from brands on here that appear to be beta versions and actually have their models labeled with 1.0, 2.0 etc. They might be ok for a one off event where the likely hood of someone wearing again post event is slim
Happy with the outcome thus far!
Great quality and price
we will be back for sure!
