The support for a lithographic printing plate obtained by performing
graining treatment including electrochemical graining treatment on an
aluminum plate, the aluminum plate is an aluminum plate which contains Fe
of 0.02 to 0.29 wt %, Si of 0.03 to 0.15 wt %, Cu of 0.020 to 0.040 wt %
and Ti of 0.050 wt % or less and whose remaining portion is composed of
Al and unavoidable impurities. In addition, the support for a
lithographic printing plate where surface area ratio and steepness
obtained from three-dimensional data found with an atomic force
microscope (AFM) each satisfies the specified conditions is excellent in
printing performance (press life, scum resistance, sensitivity and
cleaner press life or the like) and handling property (scratch
resistance, fatigue fracture strength or the like) when the lithographic
printing plate is prepared.
