Abstract
An inkjet color printer accesses image data to be printed on a pixel by pixel basis and determines the Z number of drops of different color inks to distribute per pixel over a predetermined number of passes in a multi-pass print mode of operation. Predetermined constraints relative to the maximum number of drops of a single ink color per pixel and per pass permit maskless drop ordering and an even distribution of ink over time per pixel.
