A sensitized lithographic printing plate comprising an aluminum substrate which has been mechanically, chemically and/or electrochemically pretreated and anodically oxidized in a conventional manner and a photosensitive copying layer which is applied to this substrate is produced by a process in which the substrate is aftertreated with an aqueous solution of a mixture of a fluoride and a hydrolysis product or condensate of a silane before application of the photosensitive copying layer. There lithographic printing plates are particularly suitable for offset printing.
