Abstract
A recording device, when n is an integer of 3 or more, controls a recording head to record n test patters from which a shift amount is acquirable between a scan and a scan different from each other on a medium in a main scanning direction, at least three test pattern is formed by a plurality of patches recorded by a plurality of scans, the n test patterns are formed so as to be different from each other in positional relationship of the plurality of patches and recorded side by side in the main scanning direction in an order different from an order in which the positional relationship of the plurality of patches gradually changes.
Claims12
A recording device including
- a recording head including a plurality of nozzles for discharging liquid onto a medium and
- a control unit for controlling the recording head, and
- the recording device being configured to perform recording on the medium by a scan for causing the recording head to discharge the liquid while moving the recording head along a predetermined main scanning direction, wherein
- the control unit controls the recording head to record n test patterns, from which a shift amount between the scan and the scan different from each other is acquirable, on the medium in the main scanning direction, where n is an integer of 3 or more,
- at least three of the test patterns is formed by a plurality of patches recorded by a plurality of the scans, and
- the n test patterns are
- formed so as to be different from each other in positional relationship of the plurality of patches and
- recorded side by side in the main scanning direction in an order different from an order in which the positional relationship of the plurality of patches gradually changes.
A recording method of performing recording on a medium by a scan for causing a recording head to discharge liquid while moving, along a predetermined main scanning direction, the recording head, the recording head including a plurality of nozzles for discharging the liquid onto the medium, the recording method comprising
- a recording control step for controlling the recording head to record n test patterns from which a shift amount between the scan and the scan different from each other is acquirable on the medium in the main scanning direction, where n is an integer of 3 or more, wherein
- in the recording control step,
- at least three of the test patterns is formed by a plurality of patches recorded by a plurality of the scans, and
- the n test patterns are
- formed so as to be different from each other in positional relationship of the plurality of patches and
- recorded side by side in the main scanning direction in an order different from an order in which the positional relationship of the plurality of patches gradually changes.
