Résumé

Several new inkjet printing applications require high throw distances or high printing speeds. In such configurations, complex airflows occur in the gap between the printhead and the substrate, potentially jeopardizing the print quality by deviating the ink droplets. To better understand the airflow effects on the droplet’s trajectories, a novel inkjet printing platform has been developed. The latter allows the full control of the different parameters, from the laser sheet intensity to the axis motion, to the fog generation, to the print head driving waveform. The system has been fully automatized and allow for large parametric study to be performed, key for unstable flows requiring for statistics.
