Calibration with a Densitometer
You can create up to seven custom gamma curves and download these
to your printer, in addition to the seven standard curves supplied with
XANTÉ’s Halftone Calibration Technology. The Linear option on the
printer’s front panel Gamma menu allows you to select Custom Gamma
0 as your printer’s default. The Gamma PPD option in the Print dialog
box allows you to select any of the custom gamma curves or any of the
standard gamma curves on a job by job basis (see “The Gamma Menu”
in chapter 5, “Gamma” in chapter 6, and “Halftone Calibration
Technology” in chapter 8 for details).
Custom curves can be used to adjust your printer’s performance to
eliminate inconsistencies due to equipment age, different inks and
media, and environmental conditions. These curves are created using
XANTÉ Command Center, the XANTÉ Linearization Tool, and a
densitometer using the following steps:
• Printing a Calibration Strip
• Using the Densitometer
• Linearizing the Densitometer Data
• Creating a Custom Gamma Curve
Printing a Calibration Strip
The first step in calibrating your printer is to print a calibration strip to
measure the printer’s current performance as a basis for the calibration.
1. Open XANTÉ Command Center and select Linearize from the
Controller menu to open the Linearize window.
