Abstract

A printing method includes the steps of: receiving a color image and separating the color image into a plurality of distinct color planes; dithering a first distinct color plane to obtain dot data for the first distinct color plane; dithering a second distinct color plane to obtain dot data for the second distinct color plane; providing the dot data for the first distinct color plane to a first print head cartridge for printing by a plurality of nozzle rows of the first print head cartridge; and providing the dot data for the second distinct color plane to a second print head cartridge positioned downstream from the first print head cartridge in a direction of print media propagation, the dot data for the second distinct color plane for printing by a plurality of nozzle rows of the second print head cartridge.
