Abstract
A lithographic printing plate support in which surface unevenness due to surface treatment has been suppressed and a presensitized plate of excellent sensitivity are produced from an aluminum alloy plate containing iron, silicon, titanium and boron by specifying the state in which TiBparticles are present in the surface layer and the width of the crystal grains, and by having specific indicators relating to the respective concentrations of iron and silicon in the surface layer following graining treatment fall within specific ranges. In a method of manufacturing the lithographic printing plate support, an aluminum alloy melt having specified alloying ingredients is subjected to a specified casting process to have the amount of the alloying ingredients in solid solution following cold rolling fall within specified ranges.
