1. , a kind of ink discharge control method of microfluid is characterized in that, by adjusting ink-jet head driving waveform, improves the stability of ink droplet that described ink gun sprays, and its step comprises:

  • Set one and drive energy range, comprising a lower critical drives on the energy and between the critical driving energy, when the driving energy that nozzle bore of described ink gun drives energy greater than described lower critical, promptly spray ink droplet, when critical driving energy, the nozzle ejection ink droplet of ink gun then begins to break imperfect the driving energy that nozzle bore of described ink gun greater than described;

    One main drive waveforms is provided, and the driving energy of described main drive waveforms drives energy and described going up between critical driving energy between described lower critical;

    More than one preheating waveform is provided, and the driving energy of described preheating waveform drives energy less than described lower critical, the driving energy of described preheating waveform be described main drive waveforms the driving energy 1/2 to 1/20;

    AndAdd among described main drive waveforms that to drive energy more than one section be that time interval more than 0 is as inner cooling stage, described main drive waveforms is cut at least two waveforms, thereby prolong ink droplet by being heated to the ejection time before, constitute complete bubble, strengthen the strength of ink droplet jetting nozzle face.
