Abstract:
The present invention provides a lithographic printing plate precursor that enables a lithographic printing plate formed therefrom to have excellent image visibility and a long press life, as well as a lithographic printing plate manufacturing method and a printing method. The lithographic printing plate precursor of the invention is a lithographic printing plate precursor including an aluminum support and an image recording layer, the aluminum support includes an aluminum plate and an anodized film of aluminum formed on the aluminum plate, the anodized film is positioned closer to the image recording layer than the aluminum plate is, the anodized film has micropores extending in a depth direction of the anodized film from a surface of the anodized film on the image recording layer, the micropores have an average diameter of more than 10 nm but not more than 100 nm at the surface of the anodized film, and the surface of the anodized film on the image recording layer side has a lightness L* of 70 to 100 in a L*a*b* color system.

Claim (Index 1):
A lithographic printing plate precursor comprising an aluminum support and an image recording layer,\n wherein the aluminum support includes an aluminum plate and an anodized film of aluminum formed on the aluminum plate, wherein the anodized film is positioned closer to the image recording layer than the aluminum plate is, wherein the anodized film has micropores extending in a depth direction of the anodized film from a surface of the anodized film on the image recording layer side, wherein the micropores have an average diameter of more than 10 nm but not more than 100 nm at the surface of the anodized film, wherein the surface of the anodized film on the image recording layer side has a lightness L* of 70 to 100 in a L*a*b* color system, wherein each of the micropores has a large-diameter portion which extends from the surface of the anodized film to a depth of 10 to 1000 nm and a small-diameter portion which communicates with a bottom of the large-diameter portion and extends to a depth of 20 to 2,000 nm from a communication position between the small-diameter portion and the large-diameter portion, wherein an aperture average diameter of the large-diameter portion at the surface of the anodized film is 15 to 100 nm, and wherein an aperture average diameter of the small-diameter portion at the communication position is not more than 13 nm.
