A first try at full colour gum bichromate printing. For each colour in the CMYK sequence, a separate negative was used. I chose a pinhole image, probably not the smartest thing to do.
On the left is the final image. The second image is a cyanotype. It is the first layer (C) in the CMYK sequence. Or, in this case, CYMK. Because the third image is the result of a layer of Windsor & Newton Transparent Yellow gum bichromate (Y) over the cyanotype. The fourth image is a layer of Windsor & Newton Alizarin Crimson gum bichromate (M) over the previous two layers. Last, the final image again. Printed over lightly with Windsor & Newton Lamp Black gum bichromate (K).
All layers were brush coated on Fabriano Artistico 300 gr extra white hot pressed water colour paper.
