PROBLEM TO BE SOLVED: To provide a method for producing an aluminum support for a lithographic printing plate having high levels of plate wear and fouling performance, the aluminum support for the lithographic printing plate, and a lithographic printing original plate. SOLUTION: In the method for producing the aluminum support for the lithographic printing plate, at least one side of an aluminum plate is subjected in turn to mechanical surface roughening treatment, alkali etching treatment (1), death mat treatment (1), electrolytic surface roughening treatment in a nitric acid aqueous solution (1), alkali etching treatment (2), death mat treatment (2), electrolytic surface roughening treatment in a hydrochloric acid aqueous solution (2), alkali etching treatment (3), death mat treatment (3), and anodic oxidation treatment for surface roughening treatment. The aluminum support for the lithographic printing plate and the lithographic printing original plate are provided. |
