- Thread-topic: EFI Offset Proofpaper 9200 Semimatt
I have seen discoloration in a couple papers from exposure to other
materials or pollution. I had a proof in a dark drawer for over two years
that had yellowed considerably. I think I read a Wilhelm paper on yellowing
that is not related to light exposure. I also left the rubber pad that xrite
uses to ship DTP41s on a test proof for a couple weeks. It left a very
distinct mark where it touched the paper.
