Gum Bichromate printing process layer by layer from start to finish.
Pigments: Schmincke watercolor; Permanent Carmine for M, Cadmium Yellow Middle for Y and Phthalo Blue for C and Winsor Newton's Lamp Black for B
Thanks. Two layers of cyanotype, three sets of C, M, Y and one layer of black at 1 1/2 hours per layer for a total of 18 hours (I usually work on three prints at the same time).
That was 9 layers of gum over two layers of cyanotype and a layer of black at the end. I am using a 4 inch foam brush to coat and an inexpensive 4 inch Hake brush to even out the coating afterwards.
