Abstract
A print area is divided into pixel blocks, each consisting of a plurality of pixels. Tone reproduction is performed with different density inks for cyan and magenta by a method in which the pixels in each pixel block are correlated on a one-on-one basis with the ejection positions of a plurality of different density inks, and different density dots are formed at each pixel position. Large dots extending across a plurality of pixels are formed with yellow and black inks.
