Awhile ago I asked about framing without using glass and got some useful information. But I recently heard about Hahnemühle Varnish , which they describe as a "protective varnish for canvas inkjet prints."
Now, I don't print on canvas (don't like the look for my work) and I don't print inkjet. I use bayphoto.cam (via smugmug) and I'm quite happy with their work. I have them print to Kodak Endura paper, using the metallic version 75% of the time.
I've contacted Hahnemühle to ask about this varnish on photos, not canvas ink-jets, but I'm wondering if there are any other products which would perform a similar function? (I'll update this question when I hear back from Hahnemühle.)
I heard back from Hahnemühle, as expected, they said it was developed for canvas inkjets and was only tested on canvas inkjets. Oh well, I had hope...
