In the Device Settings tab’s PDL Settings dialog box, if GDI compatible mode is
selected, then Overprint is selected automatically.
Adjust Calibration
Use this option to set and make adjustments to the Pattern shading and Text
contrast for each individual security watermark. You can print sample calibrations to
help you determine the appearance of the security watermark.
The quality and effectiveness of the printed and photocopied security watermark is
dependent on the particular printing system and the settings used. Before printing a
security watermark it is necessary to adjust the calibration, and then print calibration
pages.
Calibration should be adjusted (and calibration pages printed) under these
circumstances:
• Before using the Security Watermark feature the first time for each standard or
custom security watermark.
• When the toner is replaced.
• After periods of heavy printing activity.
• When the physical printing device is replaced.
• After changing the background pattern.
• For color models, you must also make adjustments to the calibration if you
change the Watermark color. The Pattern Shading and Text contrast values
of the previously selected color may not produce the best results with a newly
selected color.
