Paper Abstract

To appreciate the contribution of Dr. Neugebauer, it is useful to understand the art of color reproduction in printing as it was practiced in the United States from 1930 to 1940. Color printing by lithography, letterpress, and gravure in the 18th century was an art form. Color printing plates were created and printed by artists. Dramatic results required the use of several plates. In the early part of the century J.C. LeBlon made color prints using four plates, red, yellow, blue and black. He is often credited with the theory of three-color printing which states that all colors can be produced with this limited palette. His ideas and the method of producing images by hand engraving continued to be the practice even after photomechanical processes were well developed, and the practice survived well into the 20th century.
