PROBLEM TO BE SOLVED: To dispense with a place for installing an operating device by providing an ink volume adjusting device on a sheet delivery part. SOLUTION: A print quality control device 20 for adjusting an ink supply to be used for printing sheets 11 is provided at the upper part of a sheet delivery device 4. This control device 20 is structured of a case 21 which is fixed to the upper part of a sheet delivery frame 13 and is of an almost triangular shape as viewed laterally with an open top, an operating panel 22 covering this upper opening, a control part internally mounted in the case 21 and the like. During trial printing, printed sheets 11 are extracted from the sheet delivery device 4 as samples for regular printing each time the specified number of sheets is printed and the extracted sheets are disposed on a print checking table. The trial print sample and the regular print sample are visually compared. When any difference between these samples is recognized, the adjustment of an ink furnished volume, water supply and the registration of the positions at the top and the bottom and to the right and the left of the rotary press are performed by operating the touch panel of a display and the push buttons of an operating part. In this case, as the operating panel 22 is mounted above the sheet delivery device 4, an operator need not move to reach the operating panel 22. |
