Title: Banding reduction in multipass printmodes

Abstract: A swath printer and multipass printing method for improving print quality.The printer minimizes dot placement errors on a printed medium due todepositing drops of ink from lower quality printhead nozzles by providinga printmask having a mask pattern which enables those nozzles mostsusceptible to dot placement error to print relatively fewer times, andwhich enables other nozzles less susceptible to dot placement error toprint relatively more times. Such a printer and method does not requirethe use of fractional print modes having a corresponding reduction inthroughput.
