ABSTRACT:
Two sets of recording heads capable of applying ink of cyan (C), magenta (M), and yellow (Y) and of forming relatively large dots and relatively small dots are arranged in symmetry in a scanning direction and orders of colors C and M ejected in respective dot sizes onto a pixel of a secondary color are set to symmetric orders (C→M and M→C). This makes the application orders of ink for either dot size symmetric in each pixel of secondary color and thus there is no difference between application orders in formation of the pixel by either forward or backward scanning, whereby occurrence of uneven color due to the application orders of ink can be reduced.
