INK JET PRINTING APPARATUS AND INK JET PRINTING METHOD

摘要

An object of the present invention is to provide an ink jet printing apparatus which can prevent possible stripe-like density unevenness in a joint in a print head constructed by joining a plurality of chips together even if the print head is inclined to the regular position of the print head. The present invention uses a print head having the nozzle arrays being shifted in a direction in which the nozzles are arranged, so as to have overlapping portions in a direction orthogonal to the nozzle arranging direction. The present invention controls an ink ejecting operation of the nozzles in the overlapping portions between the plurality of nozzle arrays on the basis of an angle between the nozzle array arranging direction and a direction orthogonal to the direction in which the print head moves relative to the print medium.
