Abstract
The invention provides an apparatus and methods of using the apparatus to transfer conductive patterns onto substrates under conditions of heat and pressure. The apparatus comprises a master mold with a printing surface on which is produced a permanent mirror image of the conductive pattern to be created. This pattern is then coated with a loosely adherent film of conductive metal, such as copper, which is transferred onto a substrate to be printed.
