ABSTRACT:
A method and apparatus for ink jet printing enables a high grade image with the reduced ununiformity of colors to be inexpensively printed. A scan of a print head is executed to apply a reacting liquid to a print medium so that the number of reacting liquid dots impacting a unit area is reduced as the scan moves from a printing start-point of the reacting liquid to a printing end-point. Then, a scan of the print head is executed to apply the coloring inks to the area printed with the reacting liquid. Simultaneously, the reacting liquid is applied to an area which precedes by one band the area printed with coloring inks. Then, the coloring inks are applied. Simultaneously, the reacting liquid is applied to the area which precedes by one band the area printed with coloring inks. An image is formed by repeating the above steps.
