I guess you all know this.. Yesterday I made 3 lith-prints (lengthy pr0cedure) ....
I've never done any mounting other than heat dry mounting, which is trouble free, once you buy the necessary stuff and get the time/temp balance right. But - lately my gallery and framing friends tell me that any kind of mounting, at least in the markets I frequent (East Coast US), depreciates collectability, due to it's permanent nature. I'm told (and will be doing this for a show upcoming) to attach the prints (linen tape) to a support surface, then cut the matte to show 1/4" around the edge of the exposed image, then just lay the matte over, and frame. True, it's not as flat, but supposedly more preferred, for what it's worth. (All acid free materials, natch.)
