Method of printing at dot density exceeding nozzle density in stationary pagewidth printhead
Abstract:
A method of printing at a dot density exceeding a nozzle density in a stationary pagewidth printhead. The method includes the steps of: (i) advancing a print medium transversely past the stationary printhead at a rate of one line per one line-time; and (ii) firing droplets of ink from predetermined nozzles in a nozzle row to create successive lines of print. Some or all of the predetermined nozzles fire droplets of ink at a plurality of predetermined different dot positions along a longitudinal axis of the printhead during one line-time, such that the printed dot density in each line of print exceeds the nozzle density.
