Abstract:
An ink jet recording apparatus for recording an image on a recording medium by ejecting ink from each of a plurality of ink ejection ports, comprising:ink ejection amount changing means for changing a size of an ink droplet elected from each ink election port;ejection pulse timing means for generating a plurality of ink ejection pulse timings, where there is ejected, during each ink ejection pulse timing, an ink droplet the size of which is changed by said ink ejection amount changing means;modulating means for modulating record data; andcontrol means for controlling the recording of an image on the recording medium by outputting the record data modulated by said modulating means synchronously with each corresponding ink ejection pulse timing generated by said ejection pulse timing means,wherein, during each ink election pulse timing, a size of a printed ink dot at a particular location on the recording medium is changed based on the size of the ink droplet ejected from one of the plurality of ink ejection ports.
