ABSTRACT:
The present invention provides a printing apparatus and method which can appropriately thin dots for printing so as to ensure a print grade. When dots of a black ink is subjected to thinned printing, the dots are thinned using output gamma correction that corrects print data so as to reduce the print density of an image. On the other hand, when dot of a color ink other than the black ink is subjected to the thinned printing, the number of dots formed per print pixel is reduced.
