摘要： A transport mechanism transports a medium in a transport direction based on a target transport amount and has a first roller provided on an upstream side in the transport direction and a second roller provided on a downstream side in the transport direction. Correction values are calculated based on an interval between the lines in the transport direction. The transport mechanism is controlled based on a corrected target transport amount after correcting the target transport amount based on the correction values. Lines are formed by ejecting ink from a first nozzle when the first roller is in contact with the medium, and ejecting ink from a second nozzle on a downstream side from the first nozzle in the transport direction when the first roller is not in contact with the medium and the second roller is in contact with the medium.

摘要： A printing method includes performing correction of an ink ejection amount for a certain area based on a correction value for a first type row region, and performing correction of an ink ejection amount for another area based on another correction value. The certain area includes a plurality of the first type row regions adjacent to each other in a transport direction of a medium. The first type row region is a region in which a dot row is formed in a movement direction that intersects the transport direction by performing a predetermined number of times a movement-and-ejection operation in which ink is ejected from a nozzle while the nozzle is moved in the movement direction. The other area is located on the downstream side in the transport direction from the certain area, and includes a plurality of second type row regions and a plurality of the first type row regions in the transport direction. The other correction value is obtained by increasing a degree of the correction based on the correction value for the first type row region as a distance from the certain area decreases. The second type row region is a region in which a dot row is formed in the movement direction by performing the movement-and-ejection operation another predetermined number of times that is more than the predetermined number of times. A ratio of the second type row regions decreases as the distance from the certain area decreases.

摘要： A medium is carried to a predetermined position in a carrying direction. A first pattern is formed on the medium with nozzles on the carrying direction upstream side of a nozzle row constituted by a plurality of nozzles lined up at predetermined intervals. After forming the first pattern, the medium is carried in the carrying direction by a target carry amount that is shorter than the length in the carrying direction of the nozzle row. Along with forming on the medium a second pattern that forms a boundary with the first pattern with nozzles on the carrying direction downstream side of the nozzle row, a third pattern is formed on the medium with the nozzles on the carrying direction upstream side of the nozzle row. After forming the second pattern, the medium is carried in the carrying direction by a target carry amount that is shorter than the length in the carrying direction of the nozzle row so that a carry amount of the medium after forming the first pattern is longer than the length in the carrying direction of the nozzle row. A fourth pattern that forms a boundary with the third pattern is formed on the medium with the nozzles on the carrying direction downstream side of the nozzle row.
