A method of making a lithographic printing plate includes the steps of (i) image wise exposing a lithographic printing plate precursor with a digitally modulated light source so as to obtain image areas in the exposed parts of the precursor and non-image areas in the non-exposed parts of the precursor, the precursor including a hydrophilic substrate and a photosensitive layer applied onto the substrate, the photosensitive layer including a diazonium compound; and (ii) contacting the exposed precursor with an aqueous solution including a water-soluble hydrophilic polymer and/or surfactant and having a pH between 3 and 9 thereby first removing the photosensitive layer in the non-image areas and depositing the hydrophilic polymer and/or surfactant onto the substrate in the non-image areas of the printing plate precursor.
