I don't think it's dye sublimation because they are saying "Dye-Infused" my old Kodak Dye-Sub used 4 ribbons.
I asked if it was a laminate and the girl "Dawn" said no, it's a coating, but then why the "High-Heat" even baking a finish in an oven does NOT take high-heat, nor does transfer sheets. Granted, "High-Heat" could be a relative term. The print is gorgeous, nice than acrylic IMHO, I was impressed.
Ps, Their disclaimer got me thinking, the print I viewed had no such flaws, however it was "only" a 16x24
