Thanks for the suggestion! I tried this before with little practice. But that wasn't with dry pigments + the black coating was a little bit on the thick side + I'm not sure if I exposed it enough. Will try again with dry pigments / longer exposure. Or better, just came into my mind; will darken the white paper with china ink! That may give better results, since the pigment particles are very fine and the ink is much darker than what I can achieve with one or two gum layes. And that would be much much faster. Is china ink waterproof? (Not a big deal if it isn't -> I can stain the paper first, then add hardened gelatin on top of it...) Regards, Loris.
