A Woodburytype is both a printing process and the print that it produces. In technical terms, the process is a photomechanical rather than a photographic one, because sensitivity to light plays no role in the actual printing. The process produces very high quality continuous tone images in monochrome, with surfaces that show a slight relief effect. Essentially, a Woodburytype is a mold-produced copy of an original photographic negative with a tonal range similar to a carbon print.
