Silverada - I will be hard pressed to ever consider this canvas. I don't know what drunk monkey they have doing QC but it's loaded with seeds and I've even had bubbles in the coating (the inkjet receptive layer, not the varnish) that make ugly little splotches that look like someone flicked a booger on it.
Great list... to this I would add:
Epson Exhibition Matte Canvas - Some rolls have quite a few actually, some rolls are perfect. I do like the canvas, but the seeds, and also imperfections with the gesso coating (although this is the term for painters I think) do bother me.
Funny what you say about the Silverada. I have a roll of the Hanhemule Metallic Canvas, and to my horror, I found the same thing. Its like a crater in the canvas! Also, I used their recommended settings, which for a Canon is Special 5, and there is so much ink pooling. I didn't know to look for this before I ran an entire 50 inches of canvas through. Its still not waterproof, and once coated, looks like any old canvas. Hence, at twice the price, waste of money!
I think I will for sure try the Simply Elegant, both the everyday and the regular one that has a better weight, although this one is a mix of cotton and poly.
