Abstract
On a region of a recording medium that is scanned by overlapping portions of overlapping heads a plurality of times, an image is recorded in at least one scan, without using ejection nozzles in one nozzle array corresponding to the overlapping portions of the overlapping heads and by using ejection nozzles in the other nozzle array corresponding to the overlapping portions.
Claims5
An inkjet recording apparatus comprising:
- a scanning unit that makes a recording head scan a recording medium in a scanning direction, the recording head including a first nozzle array and a second nozzle array arranged in a predetermined direction that intersects the scanning direction such that end portions of the first and second nozzle arrays overlap in the scanning direction, each of the first and second nozzle arrays including a plurality of ejection nozzles for ejecting ink, the plurality of ejection nozzles arranged in the predetermined direction;
- and
- a determination unit that determines, when recording an image in a region of the recording medium that is scanned a plurality of times by an overlapping portion of the first and second nozzle arrays of the recording head, which ejection nozzles of the recording head are to be used so that an image can be recorded in at least one scan, by using ejection nozzles in the second nozzle array corresponding to the overlapping portion and without using ejection nozzles in the first nozzle array corresponding to the overlapping portion, the ejection nozzles being in the overlapping portion of the recording head facing the region.
An inkjet recording apparatus comprising:
- a scanning unit that makes a recording head scan a recording medium in a scanning direction, the recording head including an overlapping portion at which end portions of first and second nozzle arrays overlap in the scanning direction, each of the first and second nozzle arrays including a plurality of ejection nozzles for ejecting ink, the plurality of ejection nozzles arranged in a predetermined direction that intersects the scanning direction;
- and
- a recording control unit that records an image by performing recording scans using ejection nozzles in the overlapping portion such that a first combination of ejection nozzles and a second combination of ejection nozzles exist, the first combination being a combination with which two ejection nozzles in the overlapping portion corresponding to each other in the scanning direction are used, the second combination being a combination with which only one of the two ejection nozzles is used,
- wherein the recording control unit determines positions of ejection nozzles to be used such that, for an identical raster of the recording medium, the first combination is used in only one recording scan and the second combination is used in the other recording scans.
