Best Choice for Sublimation Paper
Size: 13x19inch
I'm just a beginner but have been doing sublimation for about a year. Of all the papers I have tried, A-Sub is by far the best for color transfer and ease of use. I also use A-Sub for my photo printing. I am now a firm believer in their products and don't see changing.
