ABSTRACT:
An ink-jet recording apparatus reads in advance an original with an image to be recorded and, on the basis of the read image data, executes color image recording for each band while driving ink-jet heads for scanning. The apparatus obtains the requisite ink amount of each color (the cumulative number of times that ejection is effected) for recording the image of this original, C.sub.T, M.sub.T, Y.sub.T, Bk.sub.T, on the basis of which a judgment is made as to what combination of colors minimizes the ejection amount in each scanning. In accordance with the result of this judgment, inks of the colors of each combination are ejected in first and second scanning passes, whereby it is always possible to obtain the benefits of divisional recording, such as beading prevention, regardless of the kind of image to be recorded.
