Abstract:
1. A color image processing apparatus comprising: a first unit that predicts a bleeding occurrence level from input image data; a second unit that replaces pixels in a given area having boundaries between black ink and any of color inks with another pixels in accordance with the bleeding occurrence level; and a third unit that controls switching of multiple printing modes for each main scan in accordance with the bleeding occurrence level, wherein: the bleeding occurrence level is set at a first level value when it is recognized that there is a number of boundaries exceeding a first threshold value at which black pixels are adjacent to color pixels and a quantity of inks exceeding a second threshold value is used at the boundaries; and the bleeding occurrence level is set at a second level lower than the first level when it is recognized that there is a number of boundaries exceeding the first threshold value and a quantity of inks smaller than the second threshold value is used at the boundaries.
