Patent ID: 6948431

Claim:
A method for metering dampening solution in an offset press having a printing form cylinder and a printing form with ends accommodated in a channel extending in an axial direction on a peripheral surface of the printing form cylinder, the method which comprises: obtaining sensor signals with at least one sensor aimed at the printing form cylinder; processing the sensor signals in a control device and generating actuating signals for a dampening solution metering device; metering the dampening solution in accordance with the actuating signals by a dampening solution applicator roll in rolling contact with a surface of the printing form, the dampening solution applicator roll rolling over the surface of the printing form in image regions and in image-free regions thereof and over the channel in the printing form cylinder; utilizing the at least one sensor to obtain a signal representing an actual value of a width of an ink stripe in a circumferential direction of the printing form cylinder, and formed in an image-free region of the printing form immediately following a trailing edge of the channel.
