ABSTRACT:
A light-sensitive printing plate with a coating layer with an uneven pattern removable during development provided on the surface thereof, which can be brought into intimate contact with an original image in a short period of time by vacuum adhesion. The light-sensitive printing plate is produced by taking up a coating solution from a coating solution pan by a gravure roll, scraping away excess coating solution adhering to the gravure roll by a doctor blade, transferring the coating solution still retained on the gravure roll to a coating roll made of rubber with a fine uneven pattern on the surface thereof which is turning in the same direction and at the same speed as the gravure roll, and transferring the coating solution thus transferred to the coating roll to a support running at the same speed and in the same direction as the coating roll.
