Abstract: Printing heads of combinations of four ink colors and seven printing characteristic ranks are previously used to print an image for measurement, and table parameters corresponding to all of the combinations of nozzle ink colors and printing characteristic ranks are obtained on the basis of a measurement result of this image for measurement and stored in a memory.

A printing characteristic rank for each nozzle is obtained for each of four ink colors based on a measurement result of this image for measurement, and a table parameter is selected that corresponds to the same combination as the combination of the obtained printing characteristic rank of each nozzle of four ink colors, by referring to the memory.

Abstract: In order to print a unit area of a print medium by a first printing scan and a second printing scan, dither patterns are formed which can control the arrangement of dots on the print medium without adverse effects of density unevenness and graininess, that are caused by printing position displacement. Regarding first and second dither patterns, information indicating whether or not a threshold is already set to a reference pixel and one or more pixels around the reference pixel in the first dither pattern is obtained for cases where each pixel in the first dither pattern is the reference pixel. A pixel in the second dither pattern to which a predetermined pixel is to be set is determined based on the obtained information. The first and second dither patterns formed in the above manner are associated with the first printing scan and the second printing scan, respectively.

Abstract: Area information is obtained with respect to a specified color and nozzle position having color unevenness. Then, coordinate information indicating a nozzle position corresponding to the above area information is obtained in a printing head or nozzle array corresponding to an ink color relating to the specified color information. Next, the number of candidate correction values or candidate patches is obtained on the basis of nozzle coordinates obtained corresponding to the area, by referring to a table. In this table, for example, the number of candidate correction values is small at a nozzle position where an effect due to the variations of nozzle ejection characteristics such as a nozzle ejection volume is small and a change direction is constant, and the number of candidate correction values is large at a nozzle position where an effect due to variations of nozzle ejection characteristics is large.
