Abstract
Two sets of recording heads for applying ink of cyan (C), magenta (M), and yellow (Y) are arranged in symmetry in a scanning direction and orders of colors C and M ejected onto a pixel of a secondary color are set to symmetric orders (C→M and M→C). This makes the application orders of ink 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 even in execution of two-way color print.
