Title (EN) INK JET PRINTING HEAD
(FR) TETE D'IMPRESSION A JET D'ENCRE
Abstract:
(EN) The invention relates to an ink jet printing head and to a method for implementing such head intended particularly to the printing of large size characters. Such head has at least 2 modulation bodies (A and B), therefore at least 2 nozzles, fitted with means for adjusting each of the jets, and a single module for recovery of the ink (30) with only one return line (350). The casing (1) of the head receives on its face (50) a support for an ADP cover and additionally, in its umbilic version, a second so-called 'umbilic' cover. The method for implementation in an application for printing code bars consists in providing a cascade sequencing of printed rasters with an increasing order of sequencing of droplets and of the charge voltage, and in orienting the head so as to compensate for the inclination of the raster on the support. The invention applies to the printing of large size characters such as code bars.
(FR) L'invention concerne une tête d'impression à jet d'encre et un procédé de mise en ÷uvre de cette tête destinée notamment à l'impression de caractères de grandes dimensions. Une telle tête comporte au moins deux corps de modulation (A) et (B), donc au moins deux buses, équipés de moyens de réglage de chacun des jets, et un seul module de récupération de l'encre (30) avec une seule canalisation de retour (350). Le boîtier (1) de cette tête reçoit sur sa face (50) un support de capot ADP et, en plus, dans sa version à ombilic, un second capot dit ''d'ombilic''. Le procédé de mise en ÷uvre dans une application à l'impression de codes-barres consiste à prévoir un séquencement en cascade des trames imprimées, avec un ordre de séquencement des gouttes et de la tension de charge en ordre croissant, enfin à orienter la tête de manière à compenser l'inclinaison de la trame sur le support. L'invention s'applique à l'impression de caractères de grandes dimensions, tels que les codes-barres.
