Abstract
New procedure for obtaining lithographic clichºs for several colors, characterized by establishing a laminar base of transparent material provided at least by one of its faces with a certain granulation, on which the drawings or inscriptions that must be subject are made with a pen or brush of reproduction, using any appropriate substance of an opaque nature, followed by a graphite mine or the like rubbing gently over the desired spaces in order to obtain a kind of weft in the granulation of the base sheet.
