Patent ID: 7128381

Claim:
A microfluidic inkjet control method, by adjusting driving waveform of a print head to increase stability and reduce satellite drop occurrence of ejected ink droplets from said print head, the method comprising the steps of: setting a driving energy, which is between a lower critical driving energy and an upper critical driving energy, when the driving energy applied to said print head is greater than the lower critical driving energy, the ink droplets are ejected, when the driving energy applied to the print head is greater than the upper critical driving energy, the ink droplets ejected from said nozzle start to break and become incomplete; providing more than one preheating waveform, the driving energy of the preheating waveforms being less than the lower critical driving energy; providing a main driving waveform, driving energy of said main driving waveform is between said lower critical driving energy and said upper critical driving energy, the driving energy of the preheating waveforms ranging from ½ to 1/20 of the driving energy of the main driving waveform; and inserting more than one time intervals with driving energy greater or equal than 0 that divides said main driving waveform into more than one waveforms to execute intercooling.
