ABSTRACT:
A method of determining an operating drive voltage of an ink-jet head which has an actuator and which ejects, as a result of driving of the actuator, ink droplets toward a recording medium during a relative movement of the ink-jet head and the recording medium for performing recording, the ink-jet head being configured such that an ejection speed of the ink droplets varies depending upon a drive voltage to be applied to the actuator, the method including: recording a first record pattern as a result of driving of the actuator by application of a tentatively determined first test voltage and a second record pattern as a result of driving of the actuator by application of a second test voltage different from the first test voltage, so that the first record pattern and the second record pattern are superposed on each other; and judging whether or not the first test voltage is proper as the operating driving voltage, based on an appearance of a superposed pattern formed by superposition of the first pattern and the second pattern on each other.
