摘要: An aluminum sheet material for lithographic printing plates wherein the number of aluminum carbide particles having a circle equivalent diameter measured by the PoDFA method of 3 μm or more is four or less, the number of aluminum carbide particles having a circle equivalent diameter measured by the PoDFA method of 3 μm or more being measured by melting 3000 g of the aluminum sheet material in a crucible disposed in an electric furnace, filtering 2000 g of the molten metal through a dedicated filter, allowing 1000 g of the molten metal remaining on the filter to solidify, and measuring the number of aluminum carbide particles contained in inclusions in the molten metal deposited on the upper surface of the filter by observing a vertical section (14 mm×10 mm) of the solidified metal including the diameter (14 mm) of the filter in the center area of the filter up to a height of 10 mm above the filter using a microscope.
