PROBLEM TO BE SOLVED: To provide a computer-to-plate lithographic printing plate material, which develops few plate elongation or few plate slippage in a news offset color printing with a high-speed rotary press. SOLUTION: This computer-to-plate lithographic printing plate material includes a lithographic printing aluminum support with the tensile force and yield strength in a tensile test (the tensile speed of which is 2 mm/min) of 16.5-18.5 kg/mm<SP>2</SP>respectively, and a light-sensitive layer overlying the lithographic printing aluminum support.
