Düsenplatte für Tintenstrahldrucker und Verfahren zur Herstellung derselben

摘要

The front surface 2 of the nozzle plate 1 and the nozzle 4 to a depth d is provided with an ink repellent coating 6. The volume Vm of the space within the nozzle 4 down to the meniscus A is between 0.04 and 0.5 times the volume Vi of a jetted ink droplet. The depth d is determined by forming a dry film resist or plastic metal mask (5, 8, Figs. 1 and 3) extending into the nozzle 4 from the plate rear surface 3. The coating 6 is formed by entectoid plating or sputtering or dipping in a fluorine containing agent. <IMAGE>
