    摘要: A method for making a lithographic printing plate support including the steps of:
    - providing an aluminum support;
    - graining said support in a graining electrolyte solution;
    - treating the grained support in a desmut electrolyte solution containing hydrochloric acid by applying a direct current resulting in a charge density Q;

    characterized in that the desmut electrolyte solution has a pH 2 .
