That's an odd case Alan - newspaper inks last a VERY long time because they are cheap! - they don't bother to put drying agents into them because the newspaper has a short life. That's why even a 100 year old newspaper will smudge and the paper yellows up because it's also cheap - no bleaches and stabilisers. Perversely, quality print inks will fade with time - a few hundred years or so. Andrew >At 12:35 AM 8/26/2002 -0500, you wrote: >>"It varies by paper type.
