I have had a miserable time in my current art fair season due to the recent supply and QC problems with the usually excellent Lexjet SSMC. This has gone on way too long, IMHO.
Tried Breathing Color BC800M. Very nice QC, tonality very similar to SSMC but perhaps not as nice in the really dark gradations. But with excessive texture that may be OK for portraits but is totally unacceptable for landscapes or any sharp image. Very unsharp prints. The texture is so extreme that with any type or thickness of coating the image hazes significantly when viewed with light from your back. And the really high OBA levels create a kind of day-glow effect under fluorescent lights or daylight, and wild metamerism under different types of lighting. Except for the pretty-good QC, a not very lovable canvas. In a recent art fair under very bright fluorescent lighting I got many comments about how the images seem to be backlighted! I just tell people I'm the Master of Light.
The smoothest canvas I have used recently is Fredrix 777 Vivid. Very fine texture, the sharpest printing canvas I have ever used, as sharp as slightly textured matte papers. This would be my favorite canvas except as of the time I stopped using it Fredrix was winding the rolls rather haphazardly in a way that caused awful head strikes at the puckered edges. Which of course creates megaclogs. But when Fredrix figures out how to supply neatly trimmed rolls, I'm all theirs. Some OBA's, but not enough to create serious metamerism issues.
But honestly, in my old age I am only asking for a decent canvas with absolutely consistent Quality Control, consistently smooth Texture, and high Availability. Please, somebody, help me.
