<P>PROBLEM TO BE SOLVED: To provide a method for producing a flexographic printing plate excellent in printing quality and capable of water development, by which a relief image with sharp convexity can be formed without requiring an original film. <P>SOLUTION: A photosensitive printing plate precursor includes at least a support, a photosensitive layer containing a hydrophilic polymer, and a mask layer in this order. In the method for producing a photosensitive printing plate, there are performed, through an image mask, exposure with UV light having a wavelength of 310-400 nm, exposure with UV light having a wavelength of 200-300 nm and development in this order. <P>COPYRIGHT: (C)2010,JPO&INPIT |
