Abstract
Determination of a maximum jetting frequency for an inkjet head. The method includes generating a velocity/frequency curve for an inkjet head, and determining failure zones in the velocity/frequency curve that comprise frequencies in the velocity/frequency curve resulting in jetting failure of the inkjet head. The method further includes determining a range of maximum jetting frequencies of the inkjet head that are higher than the frequencies of the failure zones, wherein subharmonic frequencies of each of the maximum jetting frequencies are outside of the failure zones. The method further includes selecting the maximum jetting frequency for the inkjet head from the range of maximum jetting frequencies.
