Howdy, I'm thinking about the possibility of making photographic stamps, and ultimately, color separation stamps. It could be like a poor man's version of dye-transfer printing. The steps would be similar to typical photogravure except that instead of etching a copper plate you'd have to find a suitable chemical to "etch" rubber. I know nothing in this realm of chemistry, but does anything come to mind that might be suitable? What dissolves rubber? Sure this is a hare-brained idea, so feel free to crush my dreams if there's cause to do so, but I'd greatly appreciate any constructive comments. Thanks, Chris 'holmburgers' H.
