Disclosed is an offset printing machine for thick sheet papers including a printing part (10), a paper feeding part (20), a transfer part (30) and a paper discharging part (40). The printing part (10) is constructed in a manner that a PS plate (13a) formed of an aluminum plate on which a film is printed is attached onto the outer surface of a printing roller (13) that comes into contact with a plurality of ink rollers (11) and water coating rollers (12) to be rolled together, and a press roller (15) is placed under a rubber roller (14) coming into contact with the printing roller (13) to be rolled together. The paper feeding part (20) is constructed in a manner that thick sheet papers are contained in a paper feeding box (21) placed at one side of the printing part (10), the thick sheet papers being pushed by a push bar (23) to be discharged one by one through an outlet (22) at which a separating plate (22a) is set. The transfer part (30) is constructed in a manner that paper feeding rollers (31) having the press roller (15) placed between them are placed at the side of the outlet (22) of the paper feeding box (21), a plurality of guide roller (32) are placed on the paper feeding rollers (31), and belts (31a and 32a) wrap around the paper feeding rollers (31) and guide rollers, respectively. The paper discharging part (40) is constructed in a manner that paper discharging rollers (33) around which a belt (33a) is wrapped are located at one side of the transfer part (30), and a paper storage case (41) for storing printed thick sheet papers (1) is located at one side of the paper feeding rollers. |
