Never done a casein print in my life, but somebody mentioned that it can be loaded to a higher pigment content then gum. Does anybody have any experience with printing very thin layers of highly pigmented casein. WOuld they look different then gum print? I am looking for something that would look more like a watercolur wash. SOmehow gum 'dulls' the pigment luminosity that is present in a watercolur as applied straight from the tube, or diluted with water only.
