Abstract

PURPOSE:To obtain a sharp image having high resolving power without lowering a printing speed at the expression time of color mixture, by arranging ink jet heads on a carriage in such a state that nozzles are separated by a predetermined distance at every colors in the direction of crossing the moving direction of the carriage at a right angle and the positioning positions thereof are made different. CONSTITUTION:The heights of heads 1 at every colors are adjusted so that the distance l2 between adjacent dots, that is, between a black dot 5a and a yellow dot 5b, between the yellow dot 5b and a magenta dot 5c and between the magenta dot 5c and a cyan dot 5d and the pitch distance l1 between dots become l1<l2. By this method, adjacent different color dots are formed on a medium to be recorded without being brought into contact with each other and the blur and interference between different color ink dots are not generated. In forming am image on the medium to be recorded set to a platen, the cyan head 1d is driven at first to form the monochromatic image of the cyan dot 5d and the medium to be recorded is fed by a distance of (N-1).l1+l2 to form the magenta dot 5c next.
