The manufacturing of complex multi-layer circuits over large areas in a reel-to-reel configuration has been one of the driving forces in the organic electronics field. We are evaluating high-resolution flexography as a possible commercial route for the R-2-R printing of RFID tags. Concurrently, we have developed a palette of printable materials that includes printable “functional inks” and high-resolution printing plates. The very interesting properties of our conducting and semiconducting inks will be discussed. We have recently developed high-resolution, solvent resistant printing plates as a stepping-stone to high-resolution reel-to-reel electronics. Thus extending flexography into the high-resolution arena. Unlike conventional lithography, micro-contact printing; not requiring sacrificial resists, developers, and etchants; maybe compatible with a wider range of materials and substrates currently utilized in plastic electronics.
