ABSTRACT:
A method of matting a pre-sensitized printing plate is disclosed. The method is comprised of electrostatically providing fine droplets of an aqueous liquid with a resin dissolved or dispersed therein on the obverse surface or reverse surface of the pre-sensitized printing plate and, thereafter, drying the fine droplets. The method is characterized in that before and/or after the attachment of the droplets the surface of the pre-sensitized printing plate is wet. The method can be continuously performed and provides a matted surface with protuberances firmly adhered to a substrate.
