PROBLEM TO BE SOLVED: To prevent the peeling of a mat and the formation of powder by keeping the sphere diameter of mist and the surface temperature of a photosensitive planographic printing plate in an appropriate relation. SOLUTION: When an aqueous fluid is sprayed as mist on each photosensitive layer of a photosensitive planographic printing plate 10, the sphere diameter of mist L in spraying is adjusted to 16-40μm, the mist is electrostatically stuck and the temperature of the printing plate 10 is regulated to the range of 7-37 deg.C. By the control of both the sphere diameter of the mist L and the temperature of the printing plate 10, the peeling of a mat (m) from the photosensitive layer is prevented and the surface of printer glass is not contaminated. When the photosensitive planographic printing plate and a photographic original plate are overlapped and vacuum-attracted, powder does not clog a vacuum pump. |
