Methods of making micro-fluid ejection head structures. One of the methods includes providing a substrate having a plurality fluid ejection actuators on a device surface thereof. The device surface of the substrate also has a thick film layer comprising at least one of fluid flow channels and fluid ejection chambers therein. A removable anti-reflective material is applied to at least one or more exposed portions of the device surface of the substrate. A nozzle layer is applied adjacent to the thick film layer. The nozzle layer is imaged to provide a plurality of nozzles in the nozzle layer, and the non-reflective material is removed from the exposed portions of the device surface of the substrate.
