I have made couple of Lith prints together with my friend - to show him beauty of this process :). He fall in love instantly and he wants to put those prints on the wall in his apartment. Plan is to not put glass in front of the prints, but I am wondering how to protect those prints. There will be dust, and couple of hours sun also.
Lith prints are made in Foma 542 paper with Moersch easy lith.
Maybe highly diluted selenium toner? Some spray?
