<p>An ink jet printing device includes a first electrode (6), a printing head (4) of ink jet type having at least one second electrode (11-l to 11-n) facing the first electrode (6) for discharging ink (9) from the second electrode (11-l to 11-n) toward the first electrode (6) in response to a voltage applied between the first and second electrodes (6 and 11-l to 11-n), and printing control unit (13, 14-l to 14-n) for activating the second electrode (11-l to 11-n) according to dot data. The printing control unit (13, 14-l to 14-n) controls the amount of ink (9) discharged from the printing head (4) by varying the waveform of voltage applied between the first and second electrodes (6 and 11-l to 11-n) according to concentration data. </p> |
