Liquid ejecting device and conveyance amount adjustment method

A liquid ejecting device, comprising:

• an ejecting unit that includes a nozzle row ejecting liquid and is configured to move reciprocally in a first direction intersecting the nozzle row;
• a moving unit configured to move a medium and the ejecting unit relatively to each other in a second direction intersecting the first direction;
• and
• a control unit configured to perform control to cause the ejecting unit to eject the liquid, and cause the ejecting unit to move for forming a plurality of first patterns and a plurality of second patterns on the medium in the first direction, and forming a plurality of third patterns corresponding to the plurality of first patterns while changing a shifted amount by which the plurality of third patterns is shifted from the plurality of first patterns by a first shift amount in the second direction, and moreover forming a plurality of fourth patterns corresponding to the plurality of second patterns while changing a shifted amount by which the plurality of fourth patterns is shifted from the plurality of second patterns by a second shift amount smaller than the first shift amount, wherein
• a rough adjustment pattern and a fine adjustment pattern positionally associated with each other in the second direction, the rough adjustment pattern is formed of the plurality of first patterns and the plurality of third patterns, and the fine adjustment pattern is formed of the plurality of second patterns and the plurality of fourth patterns,
• the rough adjustment pattern is a pattern in which image density of a pair of patterns, which is formed of the plurality of first patterns and the plurality of third patterns corresponding to the plurality of first patterns, changes in the first direction in a first cycle, and
• the fine adjustment pattern is a pattern in which image density of a pair of patterns, which is formed of the plurality of second patterns and the plurality of fourth patterns corresponding to the plurality of second patterns, changes in the first direction in a second cycle shorter than the first cycle, the second cycle including two or more cycle changes for each first cycle of the rough adjustment pattern.
