Abstract:
1. A process for creating electrical circuits or circuit elements using imaged gravure printing plates, the process comprising: obtaining a gravure printing plate imaged by etching a substantially flat plate; mounting the imaged gravure printing plate to a printing apparatus, wherein the imaged gravure printing plate comprises an image configured to create an electrical circuit or circuit element with features of 10 microns or less, and wherein the printing apparatus comprises applying a material to be deposited on the substrate to the imaged gravure printing plate wherein the material is present in the etched areas of the imaged gravure printing plate; directly contacting the substrate with the imaged gravure printing plate to transfer the material from the imaged gravure printing plate to the substrate; and removing the substrate from contact with the imaged gravure printing plate, wherein the material forms a first patterned layer of an electrical circuit or circuit element on the substrate corresponding to the image of the imaged gravure printing plate.
