Abstract (en)
[origin: EP2353882A1] A lithographic printing plate support includes an aluminum plate and an anodized aluminum film having micropores which extend in a depth direction of the micropores from a surface of the anodized film opposite from the aluminum plate. Each of the micropores has a large-diameter portion which extends to a depth A of 5 to 60 nm from the surface of the anodized film and a small-diameter portion which communicates with a bottom of the large-diameter portion and extends to a depth of 900 to 2,000 nm from a communication position. The lithographic printing plate support has excellent scratch resistance and is capable of obtaining a presensitized plate which exhibits excellent on-press developability and which enables a lithographic printing plate formed therefrom to have a long press life and excellent deinking ability when left to stand.
