<P>PROBLEM TO BE SOLVED: To provide a high-definition photogravure offset printing machine which can perform a printing of various pictorial patterns simultaneously. <P>SOLUTION: This photogravure offset printing machine is of the following structure: On a collective plate cylinder 4 which is set adjacently in contact with a silicone blanket cylinder 2, a first to a fourth gravure plate cylinders (5 to 8), each having a recessed part 5a to 8a whose widths W1 to W4 differ from the other respectively, are set in contact with the blanket cylinder 2. In addition, the depths of the recessed parts 5a to 8a are set in the way that the depths 5a to 8a are different from each other so as to make the cross-section areas S1 to S4 of the recessed parts 5a to 8a identical. Further, the blanket cylinder 2 and the first to the fourth gravure plate cylinders 5 to 8, are enclosed by a first and a second cover 15 and 16 for preventing ink from becoming dried. <P>COPYRIGHT: (C)2012,JPO&INPIT |
