Have been using Epson Premium Canvas Matte. Sadly, the latest rolls I received have a lot more texture (and heavier weight) than previous rolls.
The older rolls had very fine texture that allowed sharp bi-directional printing. The newer rolls have the same coating but the texture is now so extreme that sharp prints are no longer possible even with uni-directional printing, and even he slightest gloss on the coating causes a galaxy of little highlights that are very objectionable IMHO.
So be sure you evaluate one of the newer rolls. The part number remains the same at S045074, but it's a whole different beast now. Doggone it Epson, why did you do that!
EDIT: And it's a lot less white, maybe the equivalent of 4 RGB units darker than the older version! AAAARRRRGHHH!!!! I was getting so committed to this canvas!
