Abstract:
1. A method of preparing an inkjet printing system comprising a print head in fluid communication with an ink reservoir and having a plurality of orifices and a corresponding plurality of associated ejection chambers, comprising: providing a substrate; disposing a photoresist material on the substrate, wherein the photoresist material is selected from epoxy-based photo resist materials and methyl methacrylate-based photo resist materials; providing a UV light source; providing a mask between the UV light source and the photoresist material; exposing the photoresist material to the UV light source to polymerize the photoresist material to form a barrier layer on the substrate, the barrier layer defining in part a plurality of fluid channels and the plurality of ejection chambers; and attaching an orifice plate over the substrate, the orifice plate including the plurality of orifices in fluid communication with the ejection chambers, wherein the orifice plate comprises a material selected from polyimides and nickel.
