PURPOSE:To obtain the photosensitive planographic printing plate which is so improved that the plate can exhibit an adequate traveling property on an exposing surface plate to be disposed horizontally. CONSTITUTION:This photosensitive planographic printing plate 8 is used for an automatic plate making machine having a mechanism of automatically transferring the photosensitive planographic printing plate on the horizontally disposed exposing surface plate. The above-mentioned printing plate is formed with projections 9 of about 5 to 50mum projecting to a nonphotosensitive surface side at least at the end on the front side orthogonal with the transfer direction on the exposing surface plate. |
