Abstract

Les canaux d'encre selectionnés d'une imprimante à jet d'encre déposant des gouttelettes à la demande sont soumis à un élargissement et à une contraction, les gouttelettes d'encre étant éjectées par application de tensions unipolaires, d'abord aux canaux sélectionnés et ensuite aux canaux non sélectionnés. D'autres tensions unipolaires, retardées en temps de 2 L/c et réglées selon un coefficient de réflexion d'ondes de pression r de l'ajutage, effectuent une annulation rapide des ondes de pression résiduelle de façon à ce que des canaux adjacents soient prêts à être actionnés avec un minimum de retard.
