Abstract
An inkjet printing system includes a print head in fluid communication with an ink reservoir and having a plurality of orifices and a corresponding plurality of associated ejection chambers. The print head includes a substrate and a barrier layer disposed on the substrate. The barrier layer defines in part a plurality of fluid channels and the plurality of ejection chambers. The barrier layer includes a material selected from epoxy-based photo resist materials and methyl methacrylate-based photo resist materials. An orifice plate is disposed over the substrate. The orifice plate includes the plurality of orifices in fluid communication with the ejection chambers. The system includes a reservoir containing an organic solvent-based ink composition, wherein the ink composition includes an organic solvent selected from C-Calcohols, C-Cketones, C-Cesters, C-Cethers, and mixtures thereof, in an amount 60% or more by weight of the ink composition.
