Abstract

There is provided a method of producing a lithographic printing plate original plate and a method for roughening a surface of an aluminum support body, wherein pits having a smaller average pit diameter and being uniform in diameter can be dispersedly formed on the surface of the aluminum support body, with a high density.
In a method for producing a lithographic printing plate original plate, the method comprising an electrolytic surface-roughening treatment step for an aluminum support body (230), an electrolysis treatment is performed in an acidic solution (210) having a dissolved oxygen concentration of 6.0 mg/l or less in the electrolytic surface-roughening treatment step.
