Abstract:
The purpose of the present invention is to suppress variance in the print quality of an inkjet recording device. In order to solve the above problem, the present invention is an inkjet recording device of a charge control type equipped with two or more nozzles which are disposed side by side in a print head, the inkjet recording device being characterized by the following: having a control unit for performing print control independently for each of a plurality of printing configurations; the control unit having an input unit whereby current values of print elements of each of the printing configurations can be periodically checked, and having an output unit whereby the print elements during a subsequent print can be modified; and in that the control unit further adjusts each of the nozzles for every print so as to cause the “charging voltage”, “deflecting voltage”, and “ink pressure” of the subsequent print to approach a reference value.
