Abstract

A system for producing a desired final halftone color. The system includes a plurality of halftone dot sets. Each dot set includes a plurality of halftone cells. Each halftone cell has a distinct number of sub-cells. Actual halftone levels of a plurality of component colors are produced by each halftone cell as a function of a number of the sub-cells within the halftone cell being selected. Combinations of the actual halftone levels of the respective component colors within each dot set producing respective actual final colors are associated with each of the dot sets. A database stores, for each dot set, the actual halftone levels for each component color produced by each halftone cell. A closest actual halftone color to the desired final halftone color is determined as a function of a combination of the actual halftone levels stored within the database for the respective component colors within one of the dot sets. The closest actual halftone color is produced using a color printer.
