Abstract:
The present invention aims at providing a lithographic printing plate precursor, a lithographic printing plate manufacturing method, a printing method and an aluminum support manufacturing method that enable the resulting lithographic printing plate to have a long tiny dot press life. The lithographic printing plate precursor of the invention is a lithographic printing plate precursor having an aluminum support and an image recording layer disposed above the aluminum support. When measured over a 400 μm×400 μm region of a surface of the aluminum support on the image recording layer side using a three-dimensional non-contact roughness tester, pits with a depth from centerline of at least 0.70 μm are present at a density of at least 3,000 pits/mm 2 ; and a surface area ratio ΔS is not less than 35%, the surface area ratio ΔS being determined using an actual area S x  obtained, through three-point approximation, from three-dimensional data acquired by measurement at 512×512 points in 25 μm square of the surface of the aluminum support on the image recording layer side by means of an atomic force microscope and a geometrically measured area S o .

Claim (Index 10):
A printing method, comprising:\n an exposure step of imagewise exposing the lithographic printing plate precursor according to  claim 1  to form exposed portions and unexposed portions; and a printing step of performing printing by supplying at least one of printing ink and fountain solution to remove the unexposed portions of the lithographic printing plate precursor having been imagewise exposed, on a printing press.
