  • Photosensitive lithographic printing plate and method for making a printing plate
    Patent number: 7316887
    Abstract: A photosensitive lithographic printing plate comprises a photosensitive layer and a protective layer formed in this order on a support, wherein the photosensitive layer has a maximum peak of spectral sensitivity within a wavelength range ranging from 390 to 430 nm, the minimum exposure for the photosensitive lithographic printing plate for image formation at a wavelength of 410 nm (S410) is at most 100 ?J/cm2, and the relation between the minimum exposure for image formation at a wavelength of 450 nm (S450) and the minimum exposure for image formation at a wavelength of 410 nm (S410) is 0<S410/S450?0.1.
