Abstract
An ink-jet recording apparatus has a print headincorporating: a nozzle, which vibrates ink at a constant cycle, jets out the ink, and atomizes the ink; an electrification electrode, which electrify an ink particle; and deflection electrodes, which deflect the electrified ink particle in a main scanning direction. The print headcarries out printing by causing the ink particle to fly to a printing workpiece W conveyed by a conveyer. Flying time of the ink particle in a printing distance La between the printing workpiece W and the print headis calculated, timing of an electrification signal supplied to the electrification electrodeis controlled in accordance with the flying time, and a printing position to the printing workpiece W is set. Thus, printing can be carried out at a predetermined position to the printing workpiece W, and printing quality can be enhanced.
