Abstract: A method of preparing a patterned micro-contact printing stamp for micro contact printing including the making of a submaster of e.g. epoxy, against which a micro-contact printing stamp from polydimethylsiloxane or other stamp forming material can be formed. The micro-contact printing stamp can then be exposed to an inking material while the micro-contact printing stamp is still against the submaster, resulting in a micro-contact printing stamp capable of making numerous impressions before the inking material is exhausted.

Abstract: An apparatus and a method for micro-contact printing on a substrate. A roll having very low drag is supported for rotation by air bearings and has a micro-contact printing stamp mounted to its outer surface. Contact between the substrate and the micro-contact printing stamp drives the roll and repeatedly imprints the pattern onto the web. In convenient embodiments, the roll is a sleeve positioned over a core with the sleeve supported for rotation by a layer of air between the sleeve and the core.
