I have a client who wants me to put a print (not drymounted) that measures 92 x 32" under plexi glass with swiss clips and a foam core backing. I have done this before with a different medium (paintings on paper) but I am beginning to wonder if this is really do-able. Won't the plexi pull away from the backing in some spots even though we have the clips on it? Once this happens I am imagining the print starting to buckle and wrinkle (since it won't be completely sandwiched) Is there a way (tape, etc) to somehow adhere the plexi to the backing board so that it doesn't seperate and the art stays completely flat without drymounting it? I am doubtful but I thought I'd ask and see if anyone of you have performed a miracle quite like this..Thank you!
