Anyone had any experiences with de-drymounting (yes I know it is not a word!) posters. Works? Doesn't work?
I've had it done on my Niagara 1-sheet. Turned out ok, but there were a lot of spots that lost artwork when they were trying to separate the paper from the foam core (they touched those up during later restoration). I think the usual approach is more or less to get it pliable (with water) and scrape the poster off...
John at Poster Mountain suggested an improved approach... he puts some sort of coating on the front of the poster that protects the artwork.
Then he scrapes it off the backing (I'm sure its more technical than I made it sound
). Afterwards, he dissolves the special coating with an enzyme leaving the poster art intact and ready to be linen mounted. Sounds cool, but I'm sure you'll pay for the improved process...
