PURPOSE:To solve a problem such as a flaw and fouling to a printing plate by forming superposing and non-superposing patterns to a superposing layer under the state, in which an original plate for photosensitive printing having the superposing layer between a support and a separate film is installed to a plate cylinder, peeling the separate film and constituting the printing plate. CONSTITUTION:The printing method is composed of a printing-image forming section A, a peeling section B and a printing section C, and a printing image pattern is formed to an original plate 12 for photosensitive printing mounted onto the circumferential surface of a plate cylinder 13 in the printing-image forming section A, and the printing-image forming section A is constituted of an optical system including an optical unit 130. The original plate 12 for photosensitive printing is formed by shaping a superposing layer 101 between a support 100 and a separate film 19, and superposing and non-superposing patterns are formed to the superposing layer 101. In the peeling section B, the separate films 19 on the original plate 12 are peeling by a separating guide 20, and the separate films 19 are recovered in a recovery tray 22. The original plate 12 is used as a printing plate by peeling the separate films 19, and printing is conducted by employing the original plate. |
