Measurement of Ink and Printing Qualities.

A means is presented here to list and measure various qualities necessary to implement statistical quality control relative to lithographic printing. This includes consideration of printing qualities from the viewpoint of the purchaser of printed matter who has the responsibility of quality standards and from the viewpoint of the lithographic printer who must establish and maintain qualities in consideration of the requirements given him. It further takes into consideration two basic categories; measurement of material, i.e., paper, ink and measurement of printed matter, i.e., general process of applying the raw material.
