ABSTRACT:
An ink jet recording method uses black ink and a plurality of inks having different colors, which have ink penetration properties different from that of the black ink. The method includes generating multi-level black recording datum on the basis of a multi-level color recording datum of a discrimination pixel, wherein a ratio of generation of black recording datum is changed in accordance with a multi-level color recording datum of a pixel marginal to the discrimination pixel; and recording a color image on the basis of the multi-level color recording datum and the multi-level black recording datum generated by the generating step.
