ABSTRACT:
The present invention provides a method for preparing an aluminum support for lithographic printing plate, the aluminum support for a lithographic printing plate obtained by the method and a presensitized plate using the same, characterized in that anodizing treatment is performed on an aluminum plate after hydrochloric acid electrolytic graining treatment if necessary, nitric acid electrolytic graining treatment are performed on the aluminum plate at a specified ratio of quantities of electricity, and with this method, a lower-purity aluminum plate could be used and a obtained support for a lithographic printing plate is excellent in press life and scum resistance when a lithographic printing plate is prepared.
