<P>PROBLEM TO BE SOLVED: To enable a stable discharge even when the vibration of a drop discharged just before still remains. <P>SOLUTION: A waveform generating means for generating a reference drive waveform to discharge ink from a parent ink nozzle generates the reference drive waveform so that the time required from a termination of the discharge waveform element till the starting end of that in the next period can be in a range of (2×N-1)/2×T<SB POS="POST">C</SB>-N×T<SB POS="POST">C</SB>(N is a natural number) when a Helmholtz period obtained from a structure of the inkjet head is T<SB POS="POST">C</SB>. <P>COPYRIGHT: (C)2013,JPO&INPIT |
