Adjusting Security Watermark Calibration
For a security watermark to be effective, it must be nearly invisible in a printed
page and clearly visible in a photocopied page. Because printing systems and
driver settings can vary, you must adjust the calibration before printing a
security watermark. Adjusting the calibration is also recommended when
changing the background pattern, replacing the toner or printing system, and
after heavy printing activity.
