<P>PROBLEM TO BE SOLVED: To provide a precursor control device of the inkjet head and its control method that enable a precursor control execution to eliminate the need of stop and clear of print data once for setting of precursor control execution without interrupting the printing even if under printing by imparting the precursor microvibration to the inkjet head at an arbitrary timing of a printing data transfer unit without setting operation; and in addition enables the optimum precursor control by preventing such problems as temperature-rise caused by continuous imparting precursor microvibration according to setting convenience by frequency control of precursor microvibration. <P>SOLUTION: There is provided the precursor control device of the inkjet head that includes an inkjet head unit that has a plurality of nozzles and a control part that controls ejection of ink from the nozzles. The control part performs imparting of precursor microvibration to each nozzle corresponding to each pixel data that composes the drawing image by selecting non-print drop drive in the paper. <P>COPYRIGHT: (C)2013,JPO&INPIT |
