  • Patent number: 9868307
    Abstract: A printing apparatus includes a carriage unit, and carries out printing on a recording medium while transporting the recording medium. The carriage unit includes a first head that discharges an ink and a second head that discharges an ink of the same color, and the second head is disposed so as to be adjacent to the first head in an x axis direction, and to overlap with the first head in a y axis direction. In an outgoing path in the reciprocation of the carriage unit, a printing density of a first image, which the first head prints, gradually decreases toward an upstream side in a transport direction of the recording medium, and the first image includes a dot group, in which at least two dots formed using the ink from the first nozzles are linked to one another in the x axis direction. In addition, in a return path in the reciprocation of the carriage unit, the second nozzles print a second image, which supplements a decrease in the printing density of the first image.
