BURST MODE ELECTROHYDRODYNAMIC PRINTING

1 . A method of printing using an electrohydrodynamic printing system comprising:

providing an electrohydrodynamic printing system including:

a nozzle that dispenses a printing fluid having a viscosity greater than 100 cP, the nozzle including a conductive portion;

a substrate that receives the printing fluid;

a voltage source that applies a voltage differential between the conductive portion of the nozzle and the substrate;

a controller configured to control the voltage source such that the printing fluid is deposited on the substrate; and

causing a drop of the printing fluid to be formed from the conductive nozzle using the controller to provide a burst mode waveform to the voltage source.

2 . (canceled)

3 . The method of claim 1 , wherein the burst mode waveform comprises a series of small width pulses followed by a large width pulse, wherein each small width pulse is not sufficient to cause drop formation by itself.

4 . The method of claim 1 , the burst mode waveform being a first burst mode waveform and the drop being a first drop, the method further comprising:

causing a second drop of the printing fluid to be formed from the conductive nozzle using the controller to provide a second burst mode waveform to the voltage source, wherein the first burst mode waveform and the second burst mode waveform have a different number of small width pulses, the first drop and the second drop having different sizes when compared to each other.
