Abstract

PURPOSE:To express the lights and shades of a printed image by a method wherein continuous two drops of ink deflected on the same side by giving similar charges are joined into one drop of ink by the use of air resistance. CONSTITUTION:Drops of ink jetted from a nozzle 1a of a charge deflection type ink jet printer are charged selectively, for example, drops of ink (1), (5), (9) are charged positively and deflected in an A direction of the recording paper 6 while continuous two groups of drops of ink (3), (4) and (7), (8) are charged negatively and deflected in a B direction of the recording paper. And, since the air resistance given to the head drops of ink (3), (7) of each group of continuous two drops of ink is greater than what is given to the following drops of ink (4), (8), the flying speed decreases gradually and the head drops are combined with their following drops of ink to prepare a concentrated image on the recording paper 6.
