Abstract
An inkjet printhead includes a faceplate mounted to a printhead body. The faceplate has a first area in which an array of inkjet nozzle openings is positioned. The area is covered with a hydrophobic coating. A second area of the faceplate outside of the array of inkjet nozzle openings is covered with a first hydrophilic coating that does not contact the hydrophobic coating covering the first area. A third area of the faceplate between the first area and the second area is covered with a second hydrophilic coating. One end of the third area contacts the hydrophobic coating and another end of the third area contacts the first hydrophilic coating to pull ink emitted onto the hydrophobic coating during a purge operation to the second area of the faceplate.
