Suppression of artifacts in inkjet printing

Abstract

A method of printing is provided. The method includes providing a travel path comprising a direction of motion of a printhead relative to a recording medium, the printhead having a linear array of nozzles positioned at a nonzero angle relative to the travel path; associating a pixel area of the recording medium with each nozzle of the linear array and a time interval during which a drop ejected from each nozzle can impinge the pixel area of the recording medium; dividing the time interval into a plurality of subintervals; grouping some of the plurality of subintervals into blocks; associating one of two labels with each block, the first label defining a printing drop, the second label defining non-printing drops; associating a drop forming pulse between consecutive selected subintervals of each block having the first label; associating a drop forming pulse between each subinterval of each block having the second label; associating a drop forming pulse between other subintervals, the drop forming pulse being between each pair of consecutive blocks; and causing drops to be ejected from each nozzle based on the associated drop forming pulses.
