Title (EN) WETTING CONTROL BY ASYMMETRIC LAPLACE PRESSURE
(FR) COMMANDE DE MOUILLAGE PAR PRESSION DE LAPLACE ASYMÉTRIQUE
Abstract: front page image
(EN)A print head configured for ejecting droplets of ink comprises a nozzle surface having arranged thereon at least one nozzle and a pattern of wetting sections and anti-wetting sections, arranged around the nozzle. The wetting sections interchange on a circular line, concentric with the nozzle, with anti-wetting sections. The pattern of wetting sections and anti-wetting sections is configured such that it provides a driving force for droplets to move away from the nozzle. The invention further relates to a printing apparatus, comprising said nozzle.
(FR)Une tête d'impression conçue pour éjecter des gouttelettes d'encre comprend une surface d'ajutage sur laquelle sont agencés au moins un ajutage et un motif de sections de mouillage et de sections de non-mouillage, agencées autour de l'ajutage. Les sections de mouillage alternent sur une ligne circulaire, concentrique avec l'ajutage, avec les sections de non-mouillage. Le motif de sections de mouillage et de sections de non-mouillage est configuré de sorte qu'il offre une force d'entraînement pour que les gouttelettes s'éloignent de l'ajutage. L'invention se rapporte en outre à un appareil d'impression, comprenant ledit ajutage.
