Abstract
A printhead system comprising an inkjet printhead and a printer controller for supplying dot data to the printhead is provided. The printhead comprises a plurality of transversely aligned color channels, each color channel comprising at least one nozzle row extending longitudinally along said printhead. Each nozzle in a color channel ejects the same colored ink. The printhead is comprised of a plurality of printhead modules with each printhead module comprising a respective segment of each nozzle row. The printer controller is programmed to supply dot data such that each of the printhead modules fires a respective segment within a predetermined segment-time. At least one of the fired segments is contained in a different color channel from at least one other of the fired segments.
