ABSTRACT:
A color identifying tape having a clear or white background with a black positive register mark and a negative mark in fixed spaced relationship thereon. The black register mark forms colored background areas shaded in each primary color, red, yellow and blue in three quadrants about the register mark with a clear area to represent black, and the negative register mark has colored positive indicia on clear background corresponding to each color on the positive register mark. The color identifying tape is placed next to the article to be photographed and is photographed with black and white film through a series of filters to record the red color, the yellow color, the blue color, and the black color on separate frames of film such that the positive register marks become negative on the film and the negative register marks become positive. This allows alignment of the films in relationship with each other and the color background areas and positive indicia identifying the color represented by the film. The films are then affixed to sheets of material in corresponding fixed relationship to photoengrave lithographic printing plates.
