Abstract
A method for producing a surface finish on an electrically conductive substrate includes transferring an ink having a plurality of electrically conductive particles onto an area of a predetermined form and/or size on a surface of the electrically conductive substrate by gravure and/or flexo printing. The ink is heated to a temperature that is higher than a melting point of the electrically conductive particles to create a melt. The melt solidifies into the surface finish on the electrically conductive substrate.
