Abstract

The ink nozzles are integrated with a surface for the outlet for a water-resistant discharge. It has been provided with a number of discharge outlets. That can emit ink and energy generating parts that can generate energy for emitting ink through the outlet. For the release of such a number There is a unique surface for the exit channel for There is a waterproof center area that surrounds a number of such discharge outlets and the hydrophobic niches formed on opposite sides of the area. Such waterproof center, at least in such a way that such hydrophobic niches will be positioned Along the direction of the arrangement of the aforementioned number of discharge channels While keeping the distance Given from the arrangement of the outlet for the discharge of a number of such Face for An ejection hole for the nozzle ejector may be provided with an area. The waterproof exterior has a number of hydrophilic niches that are spaced out. From each other in this area The aforementioned waterproof exterior is positioned on the outside of the hydrophilic recess, an ink jet pre-installed with ink nozzles.
