US Patent7081322 - Printing Plates Formed By Ink Jettable Nanopaste

Numerous printing technologies are currently being employed as a cheap alternative to support nanofabrication. Inkjet technology is a particularly favorable avenue to explore since it may be used to deposit large quantities of nanoparticles selectively without the need for the traditional (and expensive) equipment used in traditional semiconductor fabrication. This patent uses inkjeting of metallic nanoparticles to form a printing plate. Claim 1 reads:

1. A method for forming an image on a substrate comprising: providing a hydrophilic substrate; imagewise ink-jet applying onto a surface of the hydrophilic substrate a nanopaste comprising metal nanoparticles and a carrier; and treating the nanopaste to form an ink-receptive image area.
