Enter the reference points for paper stretch compensation in this tab. The reference points are the positions on the reference sheet where the compensation marks are positioned. The diagram represents the reference sheet. Mark where the position marks are placed in the reference sheet by clicking the position boxes. You must enter the distance from the left or lower sheet edge for every active position. You can take the position values from the Signa Station layout of the reference sheet or you can measure the printed reference sheet.
Note: You do not have to specify the positions of the measuring marks down to the last digit. Deviations of a few millimeters generally have no adverse effect on the compensation accuracy.
The unit of measure for the sheet size and for spacing is millimeters.
Note: For web offset printing, you must comply with special defaults for the positions of the measuring marks. Take note of the instructions in WEB Press Support.
