摘要： An orifice plate for an ink jet print-head for ejecting drops of an ink, wherein the orifice plate includes an outer surface, which has a wettability with the ink, and at least one orifice arranged in the outer surface, said orifice being configured for ejecting ink drops, each orifice having an edge, the edge defining a transition boundary between the orifice and the outer surface, wherein the wettability of the outer surface is poor near the edge of the at least one orifice and the wettability increases with increasing distance from the edge of the orifice, the increasing wettability with the increasing distance from the edge of the orifice providing a driving force for moving residual ink drops away from the edge towards a wettable region, thereby reducing the risk of disturbing the trajectories of subsequent ejected ink drops.
