Liquid ejecting device and liquid ejecting method

A liquid ejecting device that ejects a liquid through an inkjet method, and the liquid ejecting device comprising:

• an inkjet head including a plurality of nozzles arranged with positions shifted from each other in a nozzle row direction that is predetermined;
• a scanning driver that causes the inkjet head to perform a main scan of ejecting the liquid while relatively moving in a main scanning direction intersecting the nozzle row direction with respect to an liquid ejecting target;
• and
• a controller that controls operation of the inkjet head and the scanning driver,
• wherein when an abnormal nozzle which is a nozzle having an abnormal ejection characteristic is present, the controller causes another nozzle in a vicinity of the abnormal nozzle to eject the liquid of a larger amount than that in a normal time when the abnormal nozzle is not present to a part of an ejecting position where the liquid is ejectable by the other nozzle in the main scan based on a mask prepared in advance, so that an amount of the liquid to be ejected at a time of the main scan by the other nozzle becomes larger than that in the normal time, and
• the mask being data specifying the ejecting position for increasing an ejection amount of the liquid and an ejection amount to be increased at the ejecting position.
