ABSTRACT:
In a method of manufacturing an aluminum alloy plate for a lithographic printing plate by continuous casting which includes feeding an aluminum alloy melt through a melt feed nozzle between a pair of cooling rollers and rolling the aluminum alloy melt while solidifying between the pair of cooling rollers, a vessel for feeding the aluminum alloy melt to the melt feed nozzle contains the aluminum alloy melt which is adjusted in such a manner that a vertical amplitude at a level of the aluminum alloy melt existing within the vessel is 10 mm or less. This manufacturing method is capable of obtaining an aluminum alloy plate for a lithographic printing plate with a uniform surface composition and manufacturing a lithographic printing plate support having no surface defect.
