The color printer : a treatise on the use of colors in typographic printing
A late nineteenth-century trade treatise on colour printing in typography, written by John F. Earhart and published by Earhart & Richardson in Cincinnati, Ohio, in 1892 for printers and typographers. Its plates are colour-swatch charts of printed tints and overprints, including blue over orange and blue over gray, a paisley-like circular block pattern, and a paper-maker's advertisement with a butterfly, offering designers historical examples of layered colour and ornament.
