Experimental Temperature Compensation on Drop-On-Demand Inkjet Printing

The paper demonstrates the interest in using temperature compensation to stabilize drop-on-demand inkjet printing process. The influence of inkjet printing parameters on the droplet velocity and ejection stability is particularly discussed. Based on experimental results a relation between the printing parameters and kinetic property of drops is drawn. Adjusting the amplitude pulse applied to the dispenser head, the drop velocity is stable over a 15°C variation, where as it increases by 5 m/s without compensation and the print quality is so optimized.
