Abstract: A lithographic printing plate precursor, a lithographic printing plate manufacturing method, a printing method and an aluminum support manufacturing method enable the resulting lithographic printing plate to have a long tiny dot press life. The lithographic printing plate precursor includes an aluminum support and an image recording layer.

A surface area ratio ?S is not less than 35%, where ?S is determined using an actual area Sx obtained, through three-point approximation, from three-dimensional data acquired by measurement at 512×512 points in 25 ?m square of the surface of the aluminum support on the image recording layer side.
