A printing process is provided in which a conductive ink is printed over a
printed pattern formed by a coating having an additive that lowers surface
tension. Printed electrical elements and antennae (including RFID
antennae) are formed using this process. The coating with the surface
tension lowering additive is printed on a substrate in a predetermined
pattern. A conductive ink is then applied over the coating and, because of
the difference in surface tension between the coating and the substrate,
the ink flows away from the coating. The conductive ink dries between the
printed coating pattern and forms the conductive element.
