Title (EN) METHOD AND PRINT HEAD FOR FLOW CONDITIONING A FLUID
(FR) PROCEDE ET TETE D'IMPRESSION DE CONDITIONNEMENT DE L'ECOULEMENT D'UN FLUIDE
Abstract: front page image
(EN)A continuous inkjet print head jets a plurality of fluid streams from an array of multiple nozzle channels. The print head includes a flow conditioning means that establishes fully developed flow in one or more regions of the print head such that substantially equal flow conditions are created at each of the inlets of the multiple nozzle channels. The substantially equal flow conditions reduce nozzle-to-nozzle variations with respect to the required trajectories of the jetted fluids to improve jet pointing and thus lead to better print quality.
(FR)L'invention concerne une tête d'impression à jet d'encre continu, injectant une pluralité de jets de fluide à partir d'un réseau de multiples canaux de buses. La tête d'impression comprend un moyen de conditionnement de l'écoulement permettant un écoulement entier dans une ou plusieurs zones de la tête d'impression de façon à obtenir des conditions d'écoulement sensiblement égales au niveau de chacune des entrées des multiples canaux de buses. Les conditions d'écoulement sensiblement égales permettant de réduire les variations d'une buse à l'autre par rapport aux trajectoires requises des fluides injectés afin d'améliorer le jet et ainsi obtenir une meilleure qualité d'impression.
