Experimental Temperature Compensation on Drop-On-Demand Inkjet Printing
Résumé
The paper demonstrates the interest in using temperature compensation to stabilize drop-on-demand inkjet printing process. Experiments describing the influence of inkjet printing parameters on the droplet velocity and ejection stability are discussed. Experimental results have permitted to develop a relation between the printing parameters and the kinetic property of drops where a variation of temperature is compensated by an adjustment of pulse amplitude. This method allows to obtain stable drops velocity for a variation of 15°C, while without compensation the velocity increases by 5 m/s. Thus, drop ejection is stabilized and the print quality is optimized.
