Excellent Colors!

I sublimated some of my photography onto these art boards for a gallery showing coming up. These. Colors. Are. AMAZING!!! Being able to do this myself really helps me save so much money instead of having to pay a printer. Really cool, alternative way to present your photos compared to traditional paper. I was able to cut this size into quarters with a band saw. I recommend a very thin blade when cutting. I did have some chipping on the sides because the blade I had on is specifically for hard wood cutting. Highly recommend!

Perfect every time

Genuine Unisub Sublimation Hardboard is a game changer. It sublimates perfectly every time.
