If you have a good stationary supplier nearby, the stuff to ask for is "endorsing ink" which is what's used to re-ink endorsing-stamp (rubber-stamp) pads. Or use WD-40 to extract whatever life is left in the original, if it's dried up rather than exhausted. But go easy, don't add too much, and let it soak in for a while. When I ran litho printing presses (in a former life) we used a solvent called MEK (methyl ethyl ketone) to undo "blanket smashes" -- dents in the rubber offset blanket caused by crumpled paper under high pressure. It's also used to give the blanket an occasional extra-good clean. MEK is also used in the plastics industry as a solvent and to glue PVC and ABS. It shouldn't be too hard to find. Caution: it's very inflammable, it dissolves or at least attacks several types of plastic, removes ink as soon as you look at it, and also removes the natural oils from your skin, so don't wash you hands in it :-) -- Pete Peter Turnbull Dept. of Computer Science University of York
