For packing, use a piece of red press board, and above that, use paper with a smooth finish . I used to use old xray film for packing but those days are gone. Vegetable oil will work for cleanup if the ink doesn’t have a lot of dryer in it. The next step up is WD40. Ordinarily, I use ordinary paint thinner (oleum) but don’t try that biodegradeable stuff. I though that would be really cool, but it just made an awful smear of things, so I wasted my money. Chuck Wendel
