The color printer. A treatise on the use of colors in typographic printing
John F. Earhart's 1892 treatise from Cincinnati printers Earhart & Richardson, made to teach jobbing compositors and pressmen how overprinted ink films combine on press. The plates are banded specimen strips: ruled screens and solids in green, magenta, blue, vermilion and black, interrupted by small reserved diamonds, dots, discs and starburst florets.
