If it was not for the Ammonium or Potassium dichromate, carbon printing would fit the bill...Knox Unflavoured Gelatin and some sugar from the supermarket, with some ink or watercolor paint tossed in. Transfer the final image to some fixed-out photo paper that was too old (fogged) to print with.

Whoops, I guess one has to have fixer then. One could use any paper that one has coated with gelatin (but hardened, so that takes more chemicals).
