I noticed yesterday in a canvas run that the Canson canvas has much less texture of the weave than the Premier Art Satin canvas. Seems the Canson has more of a gesso-like look to the surface and the Premier is more rough/deeper in weave. The Premier once sprayed with glossy, really does sparkle where the Canson looked somewhat more of a matte finish. Both are very bright white with the Canson maybe be a bit more so than the Premier.
Drawback was a noticed a bit more ink bleeding in the Premier due to the coarser surface weave, especially in sharp light-to-dark transition edge areas. I noticed the same thing happening in the BC Silverado metallic canvas too (Don't like that paper at all due to head-strike from its edge-curl and ink bleeding. Not that much of a canvas look either. Okay, smell is awful too!).
I'd vote for a sample pack.
