<P>PROBLEM TO BE SOLVED: To provide a method of exposure recording for performing exposure processing in a supersensitized state by diluting the oxygen remaining in a recording layer disposed on a support for the purpose of forming an image and an apparatus for practicing the method. <P>SOLUTION: The method of light exposure recording on a planographic printing plate 30, wherein the planographic printing plate includes a support 32 and an image recording layer 36 as an image forming means utilizing an optical radical polymerization reaction disposed on the surface of the support of the planographic printing plate, wherein the method comprising: irradiating the image recording layer 36 with a predetermined amount of a first light, whereby the radical initiator generates a radical by reaction and the radical is quenched by the oxygen remaining in the image recording layer 36 so that the remaining oxygen in the image recording layer 36 is exhausted and disappears from the image recording layer 36 and that the image recording layer 36 is supersensitized; and then irradiating the image recording layer 36 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 36. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
