Abstract
Provided is a lithographic printing plate support that 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. The lithographic printing plate support includes an aluminum plate, and an aluminum anodized film formed thereon and having micropores which extend in a depth direction of the anodized film from a surface of the anodized film opposite from the aluminum plate. Each micropore has a large-diameter portion which extends to a depth of 5 to 60 nm (depth A) from the anodized film surface, and a small-diameter portion which communicates with the bottom of the large-diameter portion, further extends to a depth of 900 to 2,000 nm from the communication position and has a predetermined average diameter.
