Abstract
A method for setting position register and color register in a sheet-fed printing press having a control computer, which provides for one setting operation, in which both position and color register are set by the control computer. For the purposes of the setting, both the register setting elements in the printing units and the setting elements in the feeder are used. The invention is distinguished by the fact that before carrying out the setting operations, during the calculation of the travels for the register setting elements and setting elements in the feeder, an optimization comprising the travels of the register setting elements and the setting elements in the feeder is carried out in the computer.
Claims11
A method for setting a position register and a color register in a sheet-fed printing press having printing units each with respective register setting elements, a feeder with setting elements, and a control computer configured to control a travel of the register setting elements and a travel of the setting elements of the feeder, the method which comprises:
- prior to carrying out a setting operation, calculating with the control computer required travels for the respective register setting elements in each of the printing units and the setting elements in the feeder for correcting register problems between the register setting elements and the feeder, and carrying out an optimization of the travels of the respective register setting elements simultaneously with the travels of the setting elements in the feeder;
- and
- carrying out the setting operation by setting the position register and the color register with the control computer and thereby using the respective register setting elements in the printing units and the setting elements in the feeder and the optimized travels thereof.
