摘要： An aluminum alloy sheet for a lithographic printing plate which has excellent ink stain resistance, with a local defect in a photosensitive layer after long-term storage being hard to occur, and excellent the pit uniformity after a roughening and a manufacturing method thereof are provided.An aluminum alloy sheet for a lithographic printing plate containing a predetermined content of Fe, Si, Cu and Ti as well as one type or more selected from B and C, and composed of remaining Al and inevitable impurities, in which a concentration of an aluminum carbide present in the aluminum alloy sheet is not more than 8 ppm, an area occupancy of aggregation substances present on the aluminum alloy sheet surface after the roughening treatment with respect to an arbitrary circle with a radius 5 μm in the aluminum alloy sheet surface is less than 10%. In a case where the area occupancy is not less than 10%, the aggregation substances are present at a rate of 1 to 2 pieces/50 cm2.

摘要： A presensitized plate bringing about the lithographic printing plate which exhibits a high resistance to scumming and in which formation of bulges causing image dropouts is suppressed is provided with the lithographic printing plate support which includes an aluminum plate and an anodized film of aluminum provided on the aluminum plate, and has a micropore extending in the anodized film in the direction of depth from a film surface opposite with a film surface facing the aluminum plate. The micropore is sealed at least partially on its inside with protrusions made of boehmite, and the protrusions made of boehmite which are located on the anodized film have a mean height of less than 15 nm.
