摘要: A coating for an ink jet printhead front face, wherein the coating comprises a low adhesion coating, wherein when the low adhesion coating is disposed on an ink jet printhead front face surface, jetted drops of ultra-violet gel ink or jetted drops of solid ink exhibit a low sliding angle with the printhead front face surface, wherein the low sliding angle is less than about 1° to less than about 30°. In embodiments, the low adhesion coating is an oleophobic coating that exhibits a contact angle of greater than about 35° with ultra-violet gel ink or solid ink. The coating can further be used for an ink jet printhead flexure chute.
