Abstract: A composite indicator for use with overlay process color screen tints in offset color printing comprised of a composite screen made of relatively angled color screens. The respective dot patterns of the color screens have the word of the process color associated with that angle worked in by an out-of-phase dot pattern with respect to that screen background dot pattern. An overlaying color screen, when properly angled, causes, by out-of-phase moire pattern effect, the name of that color to be visually readable as a relatively lighter or darker pattern on a contrasting background.
