A method for coating select portions of a liquid jetting assembly with a hydrophobic coating comprises the steps of establishing a first pressure inside of an ink chamber of the jetting assembly; establishing a second pressure outside of the ink chamber of the jetting assembly, the inside and the outside being fluidly communicable with one another by an ink delivery channel; and introducing a composition capable of forming a hydrophobic coating outside of the ink chamber. The second pressure can facilitate formation of the hydrophobic coating on an outer surface of the liquid jetting assembly, and the first pressure can restrict the hydrophobic coating from being formed within the ink chamber.
