Title (EN) PRINT HEAD OF A PRINTER, PRINTER AND PRINTING METHOD
(FR) TÊTE D'IMPRESSION D'UNE IMPRIMANTE, IMPRIMANTE ET PROCÉDÉ D'IMPRESSION
Abstract:
(EN) The invention relates to a microfluid print head (6) of a printer (1) characterised in that the head (6) comprises a distal face (19) and: - at least one first channel referred to as injection channel (14) for injecting an ink onto a substrate (40), the injection channel (14) leading onto the distal surface (19) by a first opening referred to as injection opening; - at least one second channel referred to as suction channel (15) for sucking up the ink, among others, the suction channel (15) leading onto the distal face (19) by a second opening referred to as suction opening; - a groove defined on the distal face (19) and into which the suction opening leads; and - at least one light source (9) or optical waveguide (17) for transmitting the light emitted by a light source (9).
(FR) Tête (6) d'impression microfluidique d'une imprimante (1) caractérisée en ce que la tête (6) comprend une face (19) distale et : - au moins un premier canal appelé canal (14) d'injection pour injecter une encre sur un substrat (40), le canal (14) d'injection débouchant sur la face (19) distale par un premier orifice appelé orifice d'injection, - au moins un deuxième canal appelé canal (15) d'aspiration pour aspirer l'encre entre autres, le canal (15) d'aspiration débouchant sur la face (19) distale par un deuxième orifice appelé orifice d'aspiration, - une gorge définie sur la face (19) distale et dans laquelle l'orifice d'aspiration débouche, - au moins une source (9) de lumière ou un guide (17) d'onde optique pour transmettre la lumière émise par une source (9) de lumière.
