Have been testing a lot with BC Pura Velvet as a canvas replacement. Very similar in look to Epson Cold Press Bright, but without the OBA's. The Epson white point is just a 'tich higher and a 'tich cooler than the Pura, but Pura is a lot better down towards the d-max range and the prints are surprisingly bright and neutral looking. Pura has a slightly subtler, less polarized texture than the Epson Cold Press.
Pura coats very well with ordinary canvas varnishes which is for practical reasons is my main interest, and the reason I would use it over some other matte papers like Rag Photographique that do not varnish very well. For Pura, two generous, sprayed coats gives a nice satin-like gloss. For that matter, Epson Cold Press paper coats well too, but it takes about 3 coats to get the same level of gloss. Oh, and for those having issues with ink lifting during rolling, neither Pura nor Epson Cold Press Bright seem to have an issue with that.
Profiles from coated Pura targets show a considerable increase in gamut and a much lower d-max. Like all varnished fine art papers, coating pulls the darker tones down quite a bit and that's best compensated for via the printing profile which should be made from a carefully coated target. Very pretty paper, definitely artsy and portrait-friendly, but in no way too prissy for landscapes or hard edge subjects. If I really lay on the coatings I can get a super gloss with a look that rivals face-mounted glossies, but with some residual ripple that may or may not be a problem depending on the presentation.
If BC would give me Pura on those nice, generous 50 foot rolls just like Epson does, that would be very nice. But in any case, as a canvas veteran it sure feels nice to use media with zero manufacturing defects, yeah baby! BC and Epson are both coming through nicely on the QC.
