Abstract
One of the operational issues that are generally encountered on the print-head performance is residual vibration. For good performance of droplet, the satellite and ligament of an ink droplet must be suppressed during the jetting process. It was proved that the suppressing vibration is viable to control the droplet’s speed and volume. Two kinds of suppressing vibration with front and back position of suppressing pulse from the main pulse were investigated. The suppressing vibration was proved to be an effective way of damping the residual vibration and reducing the droplet volume and speed. By analyzing two types of actuation waveform effect on droplet quality, this paper analyzes the distinctive effect of front and back suppressing vibration on droplet quality.

Summary
Introduction applied without additional pulseThe satellite on droplet and ligament of an ink droplet can be suppressed during the jetting process. The residual vibration and crosstalk influence each other, in high drop repetition rate. This problem can cause a very large difference in droplet speed [9] & [10]. The actuation waveform of the piezoelectric element has a strong influence on the droplet ejection process, controlling both the size and velocity of the ejected droplets [11]. For reducing the residual vibration that caused satellite, the actuating waveform to eject the droplet must be properly designed [1], [4], [12] & [13]. The effect of different actuation waveform design with front and back position of the suppressing vibration was investigated by the experimental study. The waveform design with suppressing vibration that could generate the droplets with a good shape will be considered as the recommended waveform design
