Lithographic printing method

A lithographic printing method comprising:

• preparing a lithographic printing plate precursor which includes an aluminum support, and an image recording layer containing an acid color developing agent and an acid generator on the aluminum support;
• imagewise-exposing the lithographic printing plate precursor;
• supplying acidic dampening water to the exposed lithographic printing plate precursor and removing a non-image area of the image recording layer;
• and
• performing printing using a lithographic printing plate obtained by the development, with printing ink and acidic dampening water,
• wherein the aluminum support includes an aluminum plate and an anodized aluminum film disposed on the aluminum plate,
• the anodized film is positioned on a side of the image recording layer with respect to the aluminum plate, the anodized film has micropores extending from a surface of the anodized film on the side of the image recording layer in a depth direction, and
• an average diameter of the micropores in the surface of the anodized film is greater than 10 nm and 100 nm or less, and a specific surface area ΔS which is a value acquired by Equation (i) for a geometrically measured area So and an actual area Sx obtained by an approximate three-point method, based on three-dimensional data obtained by measuring 512×512 points in a range of 25 μm×25 μm on the surface of the anodized film on the side of the image recording layer using an atomic force microscope, is 15% or greater and 60% or less,
• ΔS=(Sx−S0)/S0×100(%) (i).
