Printing apparatus and calibration method

摘要

A printing apparatus and a calibration method are provided which, by using a small-capacity memory, can perform a high-speed calibration processing on data used to eject ink of the same color from a plurality of nozzle arrays. By ejecting ink of the same color from the plurality of nozzle arrays, patch is printed and, based on the printed result of the patch, a content of a print data correction processing is changed.

1. A printing apparatus for printing an image by using a print head having a plurality of first nozzle arrays and a second nozzle array, a plurality of nozzles capable of ejecting a first ink are arranged in a first direction so as to form the plurality of first nozzle arrays, a plurality of nozzles capable of ejecting a second ink of a different color from that of the first ink are arranged in the first direction so as to form the second nozzle array, the plurality of first nozzle arrays and the second nozzle array being arranged in a second direction crossing the first direction such that the second nozzle array is positioned between the plurality of first nozzle arrays with respect to the second direction, the printing being performed by ejecting the first ink from the plurality of first nozzle arrays and ejecting the ink from the second nozzle array according to print data, the printing apparatus comprising:
a test pattern printing unit that prints a test pattern including a plurality of patches, each of the patches being printed by using the plurality of first nozzle arrays capable of ejecting the first ink and without using the second nozzle array; and a determining unit that determines a correction amount for correcting the print data for ejecting the first ink by using the plurality of first nozzle arrays according to printed results of the test pattern.
