ABSTRACT:
In a multi-color printing process, measurements of the optical density of two different three-color halftone control areas are used to calculate dot gain and solid density of the cyan, magenta and yellow images. Since no single-color solid control targets are used, control targets may be hidden or camouflaged in a border or logo in the final printed product. The two control targets can consist of light and dark near-neutral gray balance targets. Alternatively, two different three-color halftone regions of the printed image can be used as control areas, eliminating the need for separate control targets. Densitometers having blue, green and red filters use the two three-color halftone control areas to provide density measurements which are used by a computer to calculate the densities of cyan, magenta, and yellow halftone images. The computer then calculates the dot gain and solid density of the process inks, which are displayed to a pressman who can make appropriate adjustments to the printing process.
