Abstract:
A method of forming a metallic pattern on a substrate is provided. The method includes applying onto a metallic surface, a chemically surface- activating solution having an activating agent that chemically activates the metallic surface; non-impact printing an etch-resist ink on the activated surface to produce an etch resist mask according to a predetermined pattern, wherein at least one ink component within the etch-resist ink undergoes a chemical reaction with the activated metallic surface to immobilize droplets of the etch-resist ink when hitting the activated surface; performing an etching process to remove unmasked metallic portions that are not covered with the etch resist mask; and removing the etch resist mask.
