A note on the art of mezzotint and mezzotint printing in colours
A 1900 treatise by A. C. Dickins, published in Los Angeles by Raymond C. Gould, explaining mezzotint engraving and colour mezzotint printing, held by the Getty Research Institute. The three plates reproduce portraits as mezzotints: a soft grey drawn head, a tinted bust in red shawl, and a coloured Mona Lisa copy. For designers they show how tonal hatching and layered colour build up soft, painterly portrait tones.
