METHOD AND DEVICE FOR ADJUSTING THE REGISTER OF A PRINTING MACHINE

摘要

The invention relates to a device and method for adjusting the register of a printing machine (1) comprising at least two inker units (D1-D4). Devices of the above-mentioned variety comprise the following components: - means (5) for applying markings (8) on the print stock (4); sensors (11) for recording the position of the applied markings (8), a computer unit for determining the deviation of the position of the markings (8) from a desired position thereof; means for generating correction signals in order to control actuators or drives, whereby the deviation of the position of the markings (8) from the desired position thereof provide a basis for the correction signals and the relative angle position of the press rollers (F1-F4) and/or the position of the linear rollers and/or the axial relative position of the press rollers (F1-F4) can be influenced by the correction signals. The invention is characterized in that information on the angle position and/or the position of the press rollers (F1-F4) in the printing machine (1) can be sent to the computer unit in order to determine the deviation of the position of the markings (8) from the desired position thereof and in that the computer unit is provided with a recomputation device which takes into account the angle position of the press rollers (F1-F4) when calculating the deviation of the press roller (F1-F4) from the desired position thereof. .
