ABSTRACT:
Disclosed is a support for a lithographic printing plate obtainable by performing at least graining treatment on an aluminum plate, having on its surface thereof, a grain shape with a structure in which a grained structure with medium undulation of 0.5 to 5 μm average aperture diameter and a grained structure with small undulation of 0.01 to 0.2 μm average aperture diameter are superimposed, and a presensitized plate provided with an image recording layer on the support for a lithographic printing plate. By using this presensitized plate, a balance between scum resistance and press life when a lithographic printing plate is produced therefrom, which has been in a trade-off relation in the past, can be maintained at a high level.
