An image recording apparatus, comprising:
- a conveyer configured to convey a recording medium in a conveyance direction;
- a carriage configured to move in a scanning direction intersecting with the conveyance direction;
- a recording head carried on the carriage and having at least three nozzle rows, each of the nozzle rows having a plurality of nozzles arrayed in the conveyance direction, the nozzle rows being configured to discharge different kinds of liquids, the at least three nozzle rows being arranged in the scanning direction;
- and
- a controller configured to control the conveyer, the carriage, and the recording head to record an image on the recording medium by alternatingly executing a recording pass, in which the recording head discharges the liquids from the at least three nozzle rows to the recording medium during the movement of the carriage in the scanning direction, and a conveyance operation in which the conveyer conveys the recording medium in the conveyance direction,
- wherein, in a case that the image is recorded, that the recording pass is executed twice continuously, and that a moving direction in the scanning direction of the carriage in one of the two continuous recording passes is different from a moving direction in the scanning direction of the carriage in the other of the two continuous recording passes,
- the controller is configured to control the conveyer to convey the recording medium in the conveyance direction in the conveyance operation such that two recording areas in the recording medium where the image is recorded by the two continuous recording passes, partially overlap with each other,
- in a preceding recording pass of the two continuous recording passes, in a case that a line image corresponding to one line, which includes a plurality of dots arranged in the scanning direction and corresponds to a first non-overlap area included in the recording area of the preceding recording pass, is recorded, and in a case that the line image does not overlap with the recording area of a succeeding recording pass of the two continuous recording passes, the controller is configured to form each of the dots in accordance with a first landing order in which each of the liquids is discharged from one of the nozzle rows in order starting from the nozzle row which is included in the at least three nozzle rows and positioned at the most downstream side in the moving direction in the scanning direction of the carriage in the preceding recording pass,
- in the succeeding recording pass of the two continuous recording passes, in a case that the line image, which corresponds to a second non-overlap area included in the recording area of the succeeding recording pass, is recorded, and in a case that the line image does not overlap with the recording area of the preceding recording pass, the controller is configured to form each of the dots in accordance with a second landing order in which each of the liquids is discharged from one of the nozzle rows in order starting from the nozzle row which is included in the at least three nozzle rows and positioned at the most downstream side in the moving direction in the scanning direction of the carriage in the succeeding recording pass, and
- in a case that the line image, which corresponds to an overlap area where the two recording areas for the two continuous recording passes overlap with each other, is recorded, the controller is configured to execute recording such that the preceding recording pass and the succeeding recording pass complement each other, and to cause the liquids to be discharged from the at least three nozzle rows such that at least part of the dots in the line image is formed in accordance with a landing order different from the first landing order and the second landing order.
