Recording apparatus and recording method

A recording apparatus that includes at least a first nozzle row and a second nozzle row that are aligned in a predetermined alignment direction, the first nozzle row including a first plurality of nozzles that are overlapped in the alignment direction with a second plurality of nozzles of the second nozzle row, and the first and second nozzle rows and a recording substrate relatively move in a relative movement direction different from the alignment direction, the recording apparatus comprising:

• a processing unit that, when a defective nozzle which forms a defective dot is included in the plurality of first nozzles of the first nozzle row, causes a first closest nozzle of the second nozzle row that is located proximate to the defective nozzle to be selected as a first complementary nozzle and a second closest nozzle of the second nozzle row that is located proximate to the defective nozzle to be selected as a second complementary nozzle,
• wherein complementary dots that complement a dot which is supposed to be formed by the defective nozzle are formed by the first complementary nozzle and the second complementary nozzle, and
• wherein the processing unit sets a ratio of complementary dots formed by a nozzle closer to the defective nozzle in positions in the alignment direction between the first complementary nozzle and the second complementary nozzle to be higher than a ratio of complementary dots formed by a nozzle far from the defective nozzle.

A recording method in which a plurality of nozzle rows in which a plurality of nozzles are aligned in a predetermined alignment direction are used and the plurality of nozzle rows and a recording substrate relatively move in a relative movement direction different from the alignment direction, the recording method comprising:

• partially overlapping, in the alignment direction, the nozzles of a first nozzle row and a second nozzle row which are included in the plurality of nozzle rows,
• including a defective nozzle which forms a defective dot in the nozzles in an overlap section of the first nozzle row with the second nozzle row,
• selecting, as a first complementary nozzle, the nozzle of the second nozzle row that is closest to the defective nozzle and selecting, as a second complementary nozzle, another nozzle of the second nozzle row that is next closest to the defective nozzle,
• forming, by the first complementary nozzle and the second complementary nozzle, complementary dots that complement a dot which is supposed to be formed by the defective nozzle, and
• setting a ratio of complementary dots formed by the first complementary nozzle with respect to complementary dots formed by the first complementary nozzle and the second complementary nozzle to be a ratio obtained depending on a distance between the defective nozzle and the first complementary nozzle in the alignment direction.
