Abstract:
1. An ink-jet recording device comprising: a recording unit configured to record an image on a recording medium using a first discharge orifice row including a plurality of arranged discharge orifices for discharging ink and a second discharge orifice row including a plurality of arranged discharge orifices for discharging ink, with relative scan between the first and second discharge orifice row and the recording medium in a scanning direction intersecting with an arrangement direction of the discharge orifices of the first discharge orifice row and the second discharge orifice row, and having ink discharged from the discharge orifices of the first and second discharge orifice row; an obtaining unit configured to obtain first information on a first amount of deviation of a recording position between a predetermined discharge orifice and other predetermined discharge orifice of the first discharge orifice row in the scanning direction, second information on a second amount of deviation of a recording position between a predetermined discharge orifice and other predetermined discharge orifice of the second discharge orifice row in the scanning direction, and third information on a third amount of deviation of a recording position between the ink discharge from the predetermined discharge orifice of the first discharge orifice row and the predetermined discharge orifice of the second discharge orifice row in the scanning direction; and a determining unit configured to determine first relative timing of ink discharge from the predetermined discharge orifice and the other predetermined discharge orifice of the first discharge orifice row in the scanning direction for recording the image, based on the first amount of deviation indicated by the first information, using the timing of the ink discharge from the predetermined discharge orifice of the first discharge orifice row, as a reference, second relative timing of ink discharge from the predetermined discharge orifice and the other predetermined discharge orifice of the second discharge orifice row in the scanning direction for recording the image, based on the second amount of deviation indicated by the second information, using the timing of the ink discharge from the predetermined discharge orifice of the second discharge orifice row, as a reference and third relative timing of ink discharge from the other predetermined discharge orifice of the first discharge orifice row and the other predetermined discharge orifice of the second discharge orifice row in the scanning direction for recording the image, based on the third amount of deviation indicated by the third information, using the timing of the ink discharge from the predetermined discharge orifice of the first discharge orifice row and the timing of the ink discharge from the predetermined discharge orifice of the second discharge orifice row as references respectively.
