A dither mask is used in a halftone process that is performed by the printer that includes the preceding and following heads. The dither mask includes preceding and following head storage regions. The preceding head storage region is used for a printing portion of the preceding head. The following head storage region is used for a printing portion of the following head. The dither mask is generated by determining, using comprehensive evaluation values, storage elements in which thresholds are to be stored under the condition that dots are permitted to be formed by the preceding and following heads at the same position in the region corresponding the overlapping regions.

[Task] To achieve reduction of the number of correction value tables.[Means for Resolution] A printing method includes: printing a test pattern, in which a plurality of pixel rows including a plurality of pixels arranged in a predetermined direction are arranged in a direction intersecting the predetermined direction, on a kind of medium; reading the test pattern printed on the kind of medium by using a reading unit; obtaining a density correction value for each pixel row on the basis of the read result of the test pattern, and creating a correction value table in which each pixel row is associated with each correction value; performing correction on each pixel row using the correction value table when the printing is performed on the kind of medium; and performing correction on each pixel row using the correction value table for the kind of medium when the printing is performed on another kind of printing target medium.

A printing apparatus includes: a first nozzle array with nozzles aligned in a predetermined direction for ejecting liquid on a medium; a second nozzle array with nozzles aligned in the predetermined direction for ejecting liquid on the medium, the second nozzle array being aligned in a direction cross to the predetermined direction of the first nozzle array; and a moving mechanism for relatively moving the first nozzle array, the second nozzle array, and the medium in the moving direction. Here, when a plurality of dot arrays disposed along the moving direction is formed in a direction cross to the moving direction with a predetermined interval therebetween by using the nozzles belonging to the first nozzle array, and a plurality of dot arrays disposed along the moving direction is formed in a direction cross to the moving direction with a predetermined interval therebetween by using the nozzles belonging to the second nozzle array, the dot arrays are formed by a specific first nozzle among the nozzles belonging to the first nozzle array and a specific second nozzle among the nozzles belonging to the second nozzle array, and have a length different from the dot arrays formed by the other nozzles.

The first head includes first nozzle rows each having a nozzle for ejecting a fluid of a first color and a nozzle for ejecting a fluid of a second color lined up in a color order in a cross direction. The second head includes second nozzle rows each having the two nozzles lined up in a color order in the cross direction. The controller controls a nozzle to dispose a plurality of color-overlapped dots to form a raster line, such that a ratio of A1 to “A1+A2” is larger than a ratio of B1 to “B1+B2” to form the raster line, where A1 and A2 donate amounts of a fluid of the first color from the first and second nozzle rows, respectively, and B1 and B2 donate amounts of a fluid of the second color from the first and second nozzle rows, respectively.
