Improvements introduced in the manufacture of pre-sensitized plates of positive action for lithographic printing, according to which a metal sheet has in at least one surface thereof a product of mutual action of the metallic substance of the sheet and a poly oxygenated anion -complex of at least one metal chosen from the groups va and via of the periodic table and, coating said mutually-acting product, a diazonium salt with oxygenated poly-complex anions, photosensitive, insoluble, organophilic, tightly bound, said salt being diazonium receptive to the ink, and when the plate is exposed to ultraviolet light through a slide, decomposed in the illuminated areas to give a material that is easily removed by washing, remaining in the areas or areas of the plate not wounded by light a firmly united image.
