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.
