Abstract: A coating provides a wetting gradient to an orifice surface, the coating having a local coverage that decreases with increasing distance from an orifice. A method is provided for applying a wetting gradient on an orifice surface. The wetting gradient is formed by providing a compound for forming a coating and locally bonding this compound to the orifice surface. A print head is provided with an orifice surface, wherein the orifice surface has a wetting gradient provided around an orifice using the method for applying a wetting gradient on an orifice surface.
