Ink control method for printing presses having short inking units

摘要

A method for closed-loop or open-loop control of ink feed in lithographic offset printing presses having at least one inking unit, a control unit and an operating element for adjusting the ink feed across a predetermined ink feed control range, includes subdividing the predetermined control range into partial ranges in the control unit. At least one adjustment parameter of the inking unit or the printing press is assigned to each partial range in the control unit. The control unit determines the appropriate partial range as a function of the ink feed selected with the operating element and adjusts the selected ink feed in the inking unit with associated adjustment parameters in the inking unit and/or in the printing press.

1. A method for closed-loop or open-loop control of an ink feed in an offset printing press having at least one inking unit, a control unit, an operating element for adjusting the ink feed across a predetermined ink feed control range, and a plurality of adjustment parameters of the at least one inking unit or of the printing press, the method comprising the following steps:
subdividing the predetermined ink feed control range into a plurality of partial ranges in the control unit, wherein the partial ranges do not overlap with each other; assigning each one of the plurality of adjustment parameters of the at least one inking unit or of the printing press to only a respective one of the partial ranges in the control unit; determining, with the control unit, an appropriate partial range as a function of the ink feed selected by the operating element; and setting, with the control unit, the selected ink feed in the at least one inking unit using the respective associated adjustment parameters in at least one of the at least one inking unit or the printing press.
