ABSTRACT:
A variation in a discharge characteristic among respective nozzles of an inkjet printer is corrected. A color correction table generating section48, (1) based upon error information (nozzle classes) representing errors of color values of outputs due to errors in ink weights for three types of dots (large, middle, and small) respectively for multiple types of ink colors (CMYK), determines a second correspondence between tone values of color-converted image data and combinations of respective recording ratios of the three types of dots so that the error is approximately zero, and (2) determines combinations of a first tone value and a second tone value so that a total ink discharge quantity according to a first correspondence (SML table recording section44a) of the first tone value representing color-converted image data and a total ink discharge quantity according to a second correspondence of the second tone value representing the color-converted image data are approximately equal. The color correction section43boutputs a first tone value upon image data in CMYK being considered as a second tone value, and provides an SML dot number determining section44bwith the output as a tone value of the image data in CMYK.
