摘要： The invention provides a printing method of printing on a printing medium. The method includes: generating dot data that represents state of dot formation at each print pixel of a print image to be formed on the printing medium by performing a halftone process on image data that represents an input tone value of each pixel making up an original image; and generating the print image by forming dots on each of the print pixels according to the dot data. The halftone process determines the state of dot formation by using a dither matrix that stores a plurality of threshold values, the plurality of threshold values being used for determining state of dot formation at each of print pixels of the print image to be formed on the printing medium according to an input tone value. The dither matrix is a matrix that stores each of the plurality of threshold values in each element such that a mutual difference in dot density formed at each predetermined print pixel group according to each input tone value falls within a predetermined range. The predetermined print pixel group is a cluster of plural print pixels corresponding to each of a plurality of element groups that are created by dividing the dither matrix into preset numbers of elements.

The method includes: generating dot data representing a status of dot formation on each of print pixels of a print image to be formed on the print medium, by performing a halftone process on image data representing a input tone value of each of pixels constituting an original image; generating the print image by combining forward pass dots with backward pass dots in a common printing area in such a manner that each main scan line includes both the forward pass dots and the backward pass dots, the forward pass dots being formed on a plurality of pixels of a first pixel group in a forward pass of main scan of a print head, the backward pass dots being formed on a plurality of pixels of a second pixel group in a backward pass of main scan of the print head. The generating dot data includes setting a halftone process condition for reducing a deterioration of image quality due to a positional misalignment between the forward pass dots formed in the first pixel group and the backward pass dots formed in the second pixel group.
