    Abstract: A method of light exposure recording on a planographic printing plate, wherein the planographic printing plate includes a support and an image recording layer provided on the support, the image recording layer includes a radical polymerization initiator, the method comprising: irradiating the image recording layer with a predetermined amount of a first light, whereby the radical initiator generates a radical, the radical is quenched by free oxygen in the image recording layer, so that free oxygen in the image recording layer is exhausted and disappears from the image recording layer and that the image recording layer is supersensitized; and then rradiating the image recording layer with a second light as a recording light modulated on the basis of image information, so as to form a latent image corresponding to the image information on the image recording layer. Also provided is an apparatus for practicing the invention.
