Printing technology is considered to be a key technology even in the field of electronics, materials processing, and bio applications. Inkjet printing is an interesting patterning technique for electronic devices because it requires no physical mask, less environmental issue, and low fabrication cost, and provides good layer-to-layer registration. Therefore, this paper presents the patterning and drop-on-demand ejection by the novel electrostatic induced inkjet printing system. First, we shows the drop-on-demand or patterning experimental set-up. Using the experimental set-up, it has patterning result of electrostatic induced inkjet printer in applied DC voltage. To further investigate the drop-on-demand jetting characteristics, the external pulse is given to the power supply and make 0.5 kHz and 0.7 kHz square wave high voltages In this result, we have successful drop-on-demand operation.
