Abstract
An ink-jet printing method, an ink-jet printing apparatus and an ink-jet printing system, which are free from the deterioration of color development effect even if a plurality of color inks are used, caused by the overlap of different color inks on a printing medium, are proposed. For this purpose, when density data quantized to several ranks are converted finally to binary data by using predetermined dot arrangement patterns, a dot arrangement pattern different from those for other color inks is prepared for a particular color ink. Accordingly, it is possible to reduce as much as possible the probability that the particular color ink is overlapped with the other inks on the printing medium, whereby the color development of the particular color ink is effectively facilitated.
