Method and apparatus for minimizing color hue shifts in bi-directional inkjet printing

摘要

An inkjet printer (100) utilizes a plurality of printheads (108) in a bi-directional, single-pass mode which deposits ink droplets (401) forming composite colors in the same sequence of droplet deposition regardless of whether the printheads (108) are moved right to left or left to right. Each printhead (108) has an axis of symmetry (720) with multiple pairs of rows of ink expulsion nozzles (210) disposed essentially parallel to each other. Each pair of nozzle rows expulses droplets of ink of a particular color and is symmetrically disposed about the axis of symmetry (720).
