I'm hoping someone can help us. We made 14 signs out of .177" clear polycarbonate with full digital print 2nd surface. The poly was outgassed over the weekend, and in some of them more than a week. 2 days outside and the rash of bubbles in the picture has appeared. We used 3M 3630-114 transparent translucent for the prints. They were printed on an HP 700W (3 layer sandwich print). I've been in the sign business since 1990, I've never had to out gas longer than 24 hours. The customer brought in a sample that was made like this, although they probably used different printers and vinyl. The sample they brought in is also polycarbonate.
