Would encapsulating the mat board and print be a good way to protect from environmental pollutants? I once read that if you want to put a print in a bathroom or kitchen, that you should frame the dry-mounted print with glass as the backing board, instead of using archival corrugated board. You then band the edge of the glass, mat board, print, mat board, glass sandwich with aluminum foil, which is then taped (with Mylar tape) to form a vapor barrier.The extra glass would add weight and cost, and one would have to be careful that the tape doesn't peek out from under the frame. Does this soundlike a viable way to minimize print deterioration due to environmental factors? -Peter De Smidt ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
