ABSTRACT:
In an apparatus for recording color images making use of a plurality of inks of different colors (Y, M, C, K), the penetrability of at least one ink is caused to differ from that of the other inks. In particular, the penetrability of an ink higher in lightness is made higher than that of another ink lower in lightness. For example, inks are prepared in such a manner that their penetrability becomes higher in the order of K<M=C<Y, thereby permitting speedy recording of clear and sharp images free from formation of inadequate feathering at boundaries between inks of different colors.
