Sci Fi novel print causing cancer

[JPS]

About 20 years ago I read a sci-fi novel about how all of a sudden there was a lot more people getting cancer, mostly like lumps on the skin. It followed a group of health professionals trying to find the answer to the mystery. It turned out that it was the actual print from books, magazines and newspapers that was causing the cancer. It was a good book to read and I would like to read it again but cannot find it and of course I do not know the title or author. Has anyone ever heard of it? Thanks.
