Abstract:
A method for incremental printing with an inkjet swath printer by depositing drops of an ink from a printhead into a pixel grid on a print medium, comprising:establishing the pixel grid by depositing the drops of the ink in multiple printing passes of the printhead over the print medium in a scan direction and advancing the medium in a media advance direction between at least some of the multiple printing passes; and printing into a specific pixel of the grid by depositing both a small number of drops in each of several of the printing passes consistently from a first group of nozzles of the printhead, and many drops rapidly during at least one of the printing passes consistently from a second group of nozzles of the printhead, wherein the first and second groups of nozzles are selected based upon expected dot placement error for different nozzles of the printhead.
