PURPOSE:To form a continuous screen on the long-sized film for a printing process by printing the screen continuously by a rotary drum while conveying the film by the upper and lower side parts of the rotary drum. CONSTITUTION:The film F for the printing process which is arranged abutting on the upper and lower side parts of the rotary drum 1 formed by combining a glass plate 3 having the screen S on its peripheral surface and a block plate 4 alternately is conveyed by the rotation of the rotary drum 1. Further, light is projected upward and downward from inside the drum 1 to print continuously the screen S of the glass plate 3 at the upper and lower side parts on the conveyed film F. Namely, a printing processed part and an unprocessed part are formed alternately at the upper side part of the drum 1 at a constant interval to the film F and the screen S is printed on the unprocessed part of the folded film F at the lower side part. Consequently, the screen is formed continuously on the film. |
