ABSTRACT:
A printing plate consisting of a base portion, a mount portion and a relief portion made of a liquid resin which is sensitive to and curable by irradiated activating rays, the plate being prepared by use of a masking sheet formed with a transmitting pattern having a contour corresponding to and slightly larger than the pattern of a negative film, a semi-transmitting pattern positioned outside the transmitting pattern and having a large contour for transmitting irradiated activating rays upon attenuation, and a blocking surface positioned outside the semi-transmitting pattern and having an effect to block the activating rays to an extent not to cure the liquid resin layer.
