Thomas Shotter Boys
(Pentonville, London, 1803 - 1874, London)
Color lithographs are usually made with one stone for each color. This poses a challenge for artists who have to envision a complex blending of tones, and for printers who then have to register or align the sheet perfectly on each stone. Thomas Shotter Boys and his printer, Charles Hullmandel, perfected the process, using four or five stones, which carefully superimposed and juxtaposed colors to create a full chromatic range and the delicacy of a watercolor. Their work established a completely new standard for color printing.
