PURPOSE:To easily and simultaneously obtain a cylindrical printing plate which has uniform quality in the circumferential direction and has no seams by supplying a photosensitive resin to the inside of a cylindrical body, rotating the cylindrical body at a high speed to uniformly stick the resin liquid in the cylindrical body and subjecting the cylindrical body to back exposure and relief exposure while said body is kept rotated. CONSTITUTION:A supply means 22 in which the photosensitive resin liquid A is contained is passed through the cylindrical body 1 and is set. While the cylindrical body 1 is rotated at a low speed by a motor 12, the supply device is gently turned upside down to pour the photosensitive resin A, then the means 22 is pulled out of the cylindrical body and a high pressure mercury lamp 10' is inserted into this position. The cylindrical body 1 is rotated at a high speed so that the photosensitive resin A is uniformly stuck to the inside surface of the cylindrical body 1 by centrifugal force. The cylindrical body 1 is subjected to back exposure and relief exposure by the irradiation of a chemical lamp 10 while the high-speed rotation of the cylindrical body is continued in this state. The lamp 10' is pulled off and the rotation of the cylindrical body 1 is stopped. A base 27 (seamless woven fabric) is inserted to the inside surface of the cylindrical body 1 and an IR lamp is inserted into the point from which the lamp 10' is removed to solidify an adhesive agent. |
