PROBLEM TO BE SOLVED: To provide a high-speed inkjet printing device with a convenient mechanism to reduce quality degradation in portions void of dots during printing without replacing an inkjet head causing the voids when the voids occur. SOLUTION: The inkjet printing device is equipped with an inkjet unit combining a plurality of line heads 28 in which a plurality of nozzles are arranged at an equal interval. An interdot clearance fine adjusting mechanism 50 makes voids inconspicuous by adjusting interdot clearances for every line head 28 causing voids when the voids occur. Only by aligning a head mark (23) of a head arranged in the interdot clearance correction spacer 19 of the mechanism 50 and causing voids with a head body mark (22), a line head 28 requiring adjustment can be moved by a prescribed amount of shift in the arrangement direction of nozzles.
