Abstract:
1. A method for transferring an ink pattern, the method comprising acts of: providing an elastomeric stamp comprising a bulk surface, at least one protruding feature having a contact surface and an edge extending from the contact surface to the bulk surface, and a barrier layer having a first affinity for ink and covering the contact surface, the edge, and the bulk surface; applying a solution of the ink and a solvent to the barrier layer, the barrier layer preventing molecules of the ink from penetrating the elastomeric stamp; first contacting for a first duration of time the contact surface with a surface of a first substrate having a second affinity for the ink higher than the first affinity; transferring only the ink from the contact surface to the surface of the first substrate as a result of the first contacting; second contacting for a second duration of time the contact surface with a surface of a second substrate having a third affinity for the ink higher than the first affinity; and transferring only the ink from the edge to the surface of the second substrate forming the ink pattern as a result of the second contacting, wherein the second contacting follows the first contacting without intervening dewetting acts.
