Abstract
A recording scan is performed through a relative reciprocation of color recording heads on a recording material. The recording heads can record with higher recording density than that of input image date. A plurality of pixels (2.times.2)are formed for each pixel of input image data. A mixed color image is recorded by multiple scans of the recording heads, in such a manner that pixels thereof (2.times.2) are not subjected to superposition of ink of two colors or more during a scan of the recording heads. Thus, it is possible to prevent an occurrence of variations in mixed color, and to record a high quality color image without increasing a recording time. Further, an amount of ink of one color may be reduced when recording a second one of the scans.
