  • Patent number: 8943963
    Abstract: A method for producing a metal thin film on a substrate includes: a step of applying an ink to a flat blanket; a first transfer step of bringing the first blanket and a letterpress having a predetermined pattern of projections into contact by a pressure compression while the flat blanked and the letterpress being disposed opposite each other, to selectively transfer a portion of the ink on the flat blanket corresponding to the projections to the letterpress; a second transfer step of bringing the flat blanket obtained after the first transfer step and the substrate into contact by pressure compression while the flat blanket and the substrate being disposed opposite each other, to transfer the ink remaining on the flat blanket to the substrate; and a step of subjecting the substrate obtained after the second transfer step to electroless plating to deposit a metal thin film on the substrate.
