ABSTRACT:
In image recording by discharging plural inks of different characteristics onto a recording medium, recording pixels to be recorded by at least one of the inks of either yellow, magenta or cyan color subjected to pixel expansion are expanded in four direction, then a logic product is calculated between the expanded pixels and the pixels to be recorded with an ink which is black not subjected to pixel expansion, and the recording pixels to be recorded by the ink which is black not subjected to pixel expansion are replaced by the pixels formed by the inks (Y, M, C) subjected to pixel expansion. Thus high-quality image recording is made possible even in case the inks of different properties are brought into mutual contact.
