More Information
Summary:A method of preparing an inkjet printing system with a print head in fluid communication with an ink reservoir and having a plurality of orifices and a corresponding plurality of associated ejection chambers includes providing a substrate and disposing a photoresist material on the substrate. A mask is provided between the UV light source and the photoresist material. The photoresist material is exposed to the UV light source to polymerize the photoresist material to form a barrier layer on the substrate. The barrier layer defines in part a plurality of fluid channels and the plurality of ejection chambers. An orifice plate is attached over the substrate. The orifice plate includes a plurality of orifices in fluid communication with the ejection chambers.
