Replying to @Sacramento History Museum We show a lot of printing in our videos, but not so much of the clean up process. Here is how we clean ink off of the ink stone after letterpress printing. We use 1K kerosene as a solvent and some shop towels for cleaning. The order of ink on the ink stone from left to right is red, yellow, blue, and purple to form a rainbow gradient of ink. This ink was used to print some prints of a Dolly Parton quote that are available in our museum store. #SacHistoryMuseum #cleaning #cleantok #museumtok #rainbow
