Abstract
An ink jet method includes causing a treatment liquid to adhere to a recording medium; a white ink to adhere to the recording medium; and a non-white ink to adhere to the recording medium. The treatment liquid, white ink, and non-white ink are applied by main scans of a recording head and sub-scans of the recording medium that intersect the main scans. The recording head includes a first nozzle group arranged in the sub-scanning direction and discharging the treatment liquid, a second nozzle group arranged in the sub-scanning direction and discharging the white ink, and a third nozzle group arranged in the sub-scanning direction and discharging the non-white ink. The second and third nozzle groups have non-overlapping portions in the main scanning direction, and one or both of the second and third nozzle groups have a portion overlapping the first nozzle group in the main scanning direction.
