Recording device and recording method

A recording method by a recording device, the recording device including:

• a recording head including a plurality of nozzle groups in which a plurality of nozzles configured to discharge liquid onto a medium are disposed in a first direction and
• a transport unit configured to transport the medium,
• the recording head including, as the plurality of nozzle groups, a first nozzle group in which a plurality of first nozzles configured to discharge an achromatic liquid are disposed, and a plurality of second nozzle groups in each of which a plurality of second nozzles configured to discharge a chromatic liquid are disposed, the chromatic liquids being liquids of chromatic colors that are mutually different,
• the plurality of second nozzle groups being disposed along the first direction,
• the first nozzle group and the second nozzle group being disposed along a second direction intersecting the first direction,
• the recording method comprising:
• a recording step for performing recording by controlling movement of the recording head and discharge of the liquid by the recording head, wherein
• in the recording step,
• when, by forward scanning being main scanning in which the recording head is caused to discharge the liquid along with forward movement along the second direction of the recording head, sub scanning being relative movement in the first direction between the recording head and the medium, and return scanning being main scanning in which the recording head is caused to discharge the liquid along with return movement along the second direction of the recording head, an image is recorded by performing the main scanning a plurality of times for a band region in the medium, and
• when, of the first nozzle group, a range of the first nozzles adjacent in the second direction to a second nozzle group, of the plurality of second nozzle groups, corresponding to a first chromatic color having a lowest discharge ratio for recording the image among a plurality of the chromatic liquids is a first range, and of the first nozzle group, a range of the first nozzles adjacent in the second direction to a second nozzle group, of the plurality of second nozzle groups, corresponding to a chromatic color other than the first chromatic color of a plurality of the chromatic colors is a second range,
• a discharge ratio of the achromatic liquid by the first range for recording the image is made higher than a discharge ratio of the achromatic liquid by any second range for recording the image.
