The character of the two canvas' is totally different! The Black Diamond Satin is a very stiff canvas, a little tougher to stretch. When using Krylon sprays, there was a gloss differential. The premium edition artist canvas (matt & water resistant) prints very nicely. And when coated with their Eclipse or other vinyl acrylic, has a nice uniform gloss. It is a thinner product, much more pliable and a breeze to stretch. I also like the much lower cost of the Premium addition, When stretched you would have a hard time differentiating. And yes, the Premium addition has slightly more texture, maybe a better way of describing it would be "different character" of texture.
