ABSTRACT:
When multilevel printing is performed by using a plurality of types of inks, which present different densities for similar colors when used for printing, and changing the types of inks and the numbers of ink droplets in printing each pixel, an ink distribution table which defines a combination of the types of inks and the numbers of ink droplets in correspondence with each gray level value is generated on the basis of input information associated with the relative densities of the respective inks. A combination to be used to print each pixel is selected on the basis of the ink distribution table, thereby printing a good grayscale image free from gray-level reversal and the like.
