Influence of the Ink-Jet Condition to the Piezoelectric Drop State of Edible Ink-Jet Ink

Abstract

The drop state of the ink-jet ink is an important factor that influences the ink-jet imaging quality, so the drop state under different voltage and frequency is researched in order to research the influence of the ink-jet condition to the drop state. The edible ink sample is printed with Spectra Polaris nozzle under different ink-jet condition including voltage and frequency, and the drop state is observed by drop observation. The result shows that while voltage increases, drop speed increases and drop volume increases first and decreases then. The duration time of drop necking state is the same under different voltage, but the tail length becomes longer if the voltage is up to 120V. The drop speed is stability under the frequency of 2KHz-4KHz, but when the frequency continues to increase, the speed shows a trend of decrease.
