Plates can be images from the negatives, the positives being used for proofing purposes. When black is used, the other three colors are reduced proportionately, so as to effect proper ink transfer on press. In order to increase contrast, a fourth separation, black, is made to darken shadow areas and grays. And the blue filter images only the blue components of the image and the resulting positive will contain its opposite, yellow. The green filter images the green areas of the image on the negative, and the resulting positive will contain its opposite, magenta. The red filter images the red areas of the image on the negative, and the positive will thus contain the complementary-or opposite-color, cyan. Each filter would expose only that primary color in the image as a film negative, and the resulting film positive would contain the complementary-or opposite-color. Before the adevent of electronic and digital prepress systems, all color separations were made photographically by exposing a full-color continuous tone image through a series of red, green, and blue filters to sheets of unexposed film. (The term color separation refers to both the process and the products of that process.) The process of color separation can be accomplished photographically, electronically, or on the desktop. Consequently, a different printing plate needs to be made of each color and this, in turn, requires separate negatives or positives. Process color printing involves overprinting halftone dots of each of these four colors in varying densities, the various combinations producing the wide range of reproducible colors.
