I was under the impression you want low sheen and almost a slight hit of luster/gloss for cnavas? I guess some instances call for it or?
I have always gone for the low gloss just a "glaze" look.
The problem with satin-like or glaze finishes is that it can haze miserably in many of the most sought-offer installation locations.
For instance, behind the reception desk where the facing wall is a sea of windows. Nothing but haze. And many living rooms and offices have spaces above their sofas with similar window-facing geometries.
For many difficult locations the choices are uncoated matte behind Optium or Museum Glass, or mega glossy surfaces, or exceedingly expensive anti-reflection face mount. Just because some treatment finish looks great in one's house or shop doesn't mean its particular surface won't make it look like defrosted cow dung in certain more challenging locations with unfortunately placed light sources.
Could go on, and on, and on... I've been stung badly by print finishes more than once. Sooner or later, every wide format print schlepper will meet his reflective Waterloo just when he was expecting his artistic
apotheosis.
PS: you can easily predict hazing failures by imagining you print is a mirror. In any situation where you could see the reflection of light sources in your mirror, you can expect some degree of surface hazing on the surface of your print. If you can see windows and other large, bright light sources in your mirror, you are SOL. Assuming you can't reposition the piece or the lights, my thinking right now is that a glossy surface that limits light source reflections to the smallest possible size is preferable to almost any kind of coated matte or semi-matte surface that resolves light sources to larger hazy areas. The only thing that is almost immune to badly placed light sources is uncoated matte paper presented either bare or behind the best grades of anti-reflection glazing. BTW all current methods of applying matte coatings create haze prone surfaces under difficult lighting geometries.
