Recording method using large and small dots

An ink jet recording method for recording an image on a recording medium by ejecting ink from each of a plurality of ink election ports, comprising the steps of:

• modulating record data;
• and
• recording an image on the recording medium by outputting the record data modulated at said modulating step synchronously with an ink ejection pulse timing of one of the ink ejection ports, to eject a different size of an ink droplet,
• wherein, during each ink ejection 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.

An ink jet recording apparatus for recording a pixel with a recording head having a plurality of ink ejection ports by recording a plurality of dots, comprising:

• driving means provided in correspondence with the ink ejection ports for sequentially ejecting, at predetermined timings, at least two inks among a plurality of inks to form a plurality of dots constituting the pixel, from the ink ejection ports of the recording head;
• changing means for changing a size of an ink droplet of each of the at least two inks sequentially ejected from the ink ejection ports by the driving means at the predetermined timings;
• and
• output means for outputting, time sequentially and synchronously with the predetermined timings, data for ejecting ink which forms the pixel and which contains information of a size of an ink droplet to be ejected from each of the plurality of ink ejection ports in an ink output order.
