INKJET PRINTHEAD

In an inkjet print head for generating a droplet of ink, the inkjet print head comprises an ink supply substrate; a droplet forming unit arranged on the ink supply substrate, the droplet forming unit having an ink inlet surface, in which ink inlet surface an ink inlet port for receiving ink from the ink supply substrate is arranged; a manifold chamber formed over the ink inlet surface of the droplet forming unit; and a filter arranged between the ink supply substrate and the manifold chamber, the filter having a first filter surface at an upstream side and having a second filter surface at a downstream side, the second filter surface being opposite to the first filter surface and filter holes extending from the first filter surface to the second filter surface. The filter is arranged in an area surrounding the manifold chamber for increasing the filter area without significantly increasing a cross-sectional size of the inkjet print head. Further, an ink flow parallel to and along the second filter surface is enabled to be generated for removing air bubbles trapped behind the filter.
