5.9.6 Calculation and input of shrinkage compensation
Due to the shrinking of the paper during the fusing process, the black portion gets slightly
displaced with respect to the color portion in CustomTone printing. This shift increases
continuously with the sheet length, causing register inaccuracies of up to 2 mm to occur in
long formats.
The shrinking of the paper depends on the quality of the respective paper (thickness,
moisture, fiber direction,...) and is different for every fusing process.
This phenomenon can be compensated with the shrinkage compensation.
Calculating vertical shrinkage compensation
You can directly enter the shrinkage factor in the operator panel as value or have it
calculated with the help of the operator panel. For calculating, two measurements are
necessary: Vertical distance of the print object with shift from the leading edge of the sheet,
and the vertical shift between the two colors within the print object.
Note
As far as possible, take the measurements on the print object, that has the largest
distance from the leading edge of the sheet. This reduces the measuring errors.
The measurements and settings must be carried out separately for leading and
trailing edge.
Proceed as follows:
1.
Select the <VarioPrint> <Configuration> <Paper> <Papers> menu at the operator
panel.
2.
Select the tab <Shrinkage compensation>.
3.
Select the page for which the setting needs to be done using the buttons in the
"Switch page" area.
4.
Click on
in the "Vertical shrinkage compensation" area.
"Calculation of shrinkage factor" window is opened.
5.
Measure the distance of the print object with shift from the leading edge of the sheet.
