Abstract
To prevent shifts in the landing positions of ink in edge regions, two adjacent nozzles to which ink is supplied from a common liquid chamber are restricted from simultaneously discharging ink.
Claims12
An inkjet recording apparatus comprising:
- a recording unit in which a plurality of nozzles for discharging ink supplied from a common liquid chamber is arranged in a first direction;
- a scan unit configured to perform a relative scan relative to a recording medium in a second direction intersecting the first direction;
- and
- an acquisition unit configured to acquire image data including at least one recording target,
- wherein, in a case where a width in the second direction of the recording target is a first number of pixels, the recording unit performs recording using a first nozzle but not a second nozzle adjacent to the first nozzle in the first direction in a single relative scan in an edge region of the recording target, and
- wherein, in a case where the width in the second direction of the recording target is a second number of pixels smaller than the first number of pixels, the recording unit performs recording using the first and second nozzles in the single relative scan in the edge region of the recording target.

An inkjet recording method comprising:
- acquiring image data including at least one recording target;
- in a case where a width in a second direction of the recording target is a first number of pixels, in a single relative scan in the second direction by a recording unit in which a plurality of nozzles for discharging ink supplied from a common liquid chamber is arranged in a first direction intersecting the second direction, and a recording medium in an edge region of the recording target, performing recording using a first nozzle but not a second nozzle adjacent to the first nozzle in the first direction;
- and
- in a case where the width in the second direction of the recording target is a second number of pixels smaller than the first number of pixels, performing recording using the first and second nozzles in the single relative scan in the edge region of the recording target.
