Embodiment Construction

[0015] Refer to the following Figure 1-5 Examples of the present invention will be described.

[0016] Such as figure 1 As shown, a paper-fed offset rotary printing machine 1 includes a paper feed device 2 that feeds paper 11 stacked on a stacker 10, printing units 3A and 3B for respective colors, and a paper conveying device 4, wherein the printing units feed Two colors are printed on the paper 11 supplied from the paper supply device 2 that conveys the paper 11 conveyed from the printing unit 3B.

[0017] In the paper supply device 2 , the paper sheets 11 stacked on the stacker 10 are sucked one by one by a suction device (not shown), and fed to the feed plate 12 . Then, the paper 11 is conveyed to the grippers of the impression cylinder (not shown) of the printing unit 3A by the swing arm shaft front gripper (not shown), and the first color is printed on the paper. The sheet 11 is also conveyed by a transfer cylinder (not shown) to the grippers of an impression cylinder...

Abstract

This invention discloses an ink supply amount control apparatus for a printing press, including a sheet delivery device, printing quality control device, measuring device, and ink amount adjusting device. The sheet delivery device delivers a sheet printed by a printing press. The printing quality control device is provided on the sheet delivery device, and at least adjusts an amount of ink to be printed on the sheet by a manual operation. The measuring device is movably provided on the printing quality control device, and measures color adjustment data for each of color patches printed in the margins of the sheet. The ink amount adjusting device includes a control unit which automatically adjusts the amount of ink to be printed on the sheet, based on the comparison result between the color adjustment data measured by the measuring device, and reference values set in advance.

Description

technical field [0001] The present invention relates to an ink supply amount control device for a printing machine that adjusts the amount of ink supplied from a printing device unit while comparing printed paper and printed samples with each other. Background technique [0002] Conventionally, in order to save space, an ink source amount control device for an operator to manually adjust the amount of ink supplied from an inking device of a printing machine is provided at a paper conveying device of a printing machine together with a printing sample table on which printed printed products are placed. above, as disclosed in US Patent No. 6,606,949 (Document 1). [0003] On the other hand, in the ink supply amount control apparatus disclosed in Japanese Patent Laid-Open No. 63-144219 (Document 2), the ink ribbon is printed on the top, bottom or center of the paper while the image is printed on the paper The blank portion extends in the transverse direction (in the same direct...
