Abstract:
1. An ink jet application device comprising: an application head having a plurality of nozzles and a plurality of actuators respectively mounted to the nozzles, and spraying ink from a nozzle by applying a certain voltage to an actuator; an information storage storing characteristic information for relating a volume of an ink-droplet to a voltage value to be applied to the actuator; a voltage calculation unit connected to the information storage, and calculating a voltage value related to the volume of the ink-droplet sprayed from the nozzle which is a voltage correcting object with reference to the characteristic information; a voltage difference calculation unit connected to the information storage and the voltage calculation unit, and calculating a voltage difference value between the calculated voltage value and a voltage value related to a specific volume of the ink-droplet; and a supply unit connected to the voltage difference calculation unit, and supplying a correction voltage obtained by adding the certain voltage to the voltage difference value to the actuator mounted to the nozzle which is the voltage correcting object.
