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 2):
The lithographic printing plate precursor according to  claim 1 ,\n wherein the surface of the aluminum support on the image recording layer side has pits having an average aperture size of 0.01 to 0.5 \u03bcm.
