Abstract:
A lithographic printing plate support includes an aluminum plate and an anodized film formed at a surface of the aluminum plate and having micropores which extend in a depth direction of the anodized aluminum film from a surface of the anodized film opposite from the aluminum plate. Each of the micropores includes a large-diameter portion and a dendritic small-diameter portion. The lithographic printing plate support has excellent scratch resistance and is capable of obtaining a presensitized plate which exhibits excellent on-press developability and enables a lithographic printing plate formed therefrom to have a long press life and excellent deinking ability after suspended printing.
