Abstract
The present invention provides a method for producing a planographic printing plate and a dummy plate for planographic printing in a CTP plate-making system, the method including: taking one product out of a pile of multiple planographic printing plate precursors piled up on a base substrate and a pile of multiple dummy plate precursors for planographic printing piled up on another base substrate, distinguishing the kind of the one product, exposing the one product to an infrared ray when the one product is a planographic printing plate precursor, and developing the one product when the one product is other than the base substrate, wherein the base substrate surface, the planographic printing plate precursor, and the dummy plate precursor for planographic printing each have a different absorption maximum in a range of 350 to 700 nm and an absorbance at the absorption maximum of 0.2 or more.
