Abstract

See full text

When recording a color image on a recording medium according to record data using black ink and color ink of a plurality of colors having a different characteristic of permeation into the recording medium from the black ink, detecting the boundary between a black image and a color image is executed. For an area where the boundary has not been detected, normal printing which can record the image at a relatively high speed is set. For an area where the boundary has been detected, multi-pass printing which can record the image at a relatively low speed is set. Thus, a drop of recording speed and bleeding at the boundary are prevented.
