Have not recently printed on Monet or Daguerre. They are both about 20 mils, and soft and supple enough to work in my 8300 even with its reduced suction abilities dues to high altitude. Both have textures that are finer and shallower than most canvases, that's something I like very much because to my eyes that improves print appearance in difficult installation locations. The weave on Monet is the finer of the two, and the weave pattern is only slightly more pronounced in one direction than in the other. It suggests a fine art paper surface. I hugely prefer that to the egregiously strong, highly polarized, corrugated looking texture in too many canvases that cause serious appearance failures in a limited but important subset of installations. Daguerre has a slightly deeper and slightly more polarized weave, but it is still in a range I could tolerate. Both are relatively expensive in the US, and very sadly the roll lengths are not quite 40 feet on 2" cores.
I have used some Photo Canvas 320 and I like it a lot. I think it's Hahnemuehle's "production" canvas product, at about twice the price of some others. A relatively subtle, relatively unpolarized weave prints very sharp for a canvas. At 16 mils thick it may or may not be challenging to stretch. I only glue mount canvas and the depth is just enough to block the darkening effects of black Gatorfoam. It takes gloss coating well, yielding a bright image. But it also looks nice uncoated, a lot like a matte fine art paper, although the Epson hot and cold press papers have better blacks in their uncoated state. When coated the weave resolves reflections to a "sea of stars" effect floating over the still contrasty image, rather than the more common "Bejing haze" effect that sort of dissolves the image to grey slime. That's my #1 reason for liking it. I like my pieces to be able to compete in difficult locations. I often do two or more installations a week, and I just hate it when my work looks like crud on the wall due to, for instance, on-axis lighting. For instance, if you ever install a piece in typical condominium with 8 foot ceiling, you can be sure there will be an absurd eye-height chandelier over the table that will wipe out every reflective object on the wall. It also comes in 65 foot rolls, minimizing the frequency of loading hassles, and giving a higher useful yield between loading losses and end-of-roll losses. And yes it has OBAs.
I have no idea how any of those canvases stretch.
Bottom line for all three of the above canvases...none shout "Hey Mom! Look! I'm on canvas!" which is what I so dislike about so many current canvases. You can print on any of those three and still hold your head high as a Fine Artist.
