Calibration With A Densitometer (Gamma) - Xante ScreenWriter 3 Manual

Calibration with a Densitometer (Gamma)

Your printer's Custom Dot Gain Calibration feature provides
densitometer support which allows you to adjust your printer's
performance to eliminate inconsistencies due to equipment age,
different toners, press inks, media, and environmental conditions. Dot
Gain Calibration provides gamma control to adjust image grayscale
values to help compensate for dot gain.
The XD-1 (XANTÉ Densitometer), combined with XANTÉ Command
Center software, measures grayscale output for calibration and proofing.
This affordable, easy-to-use densitometer will be used in this manual for
example purposes.
Seven standard curves are supplied with XANTÉ's Halftone Calibration
Technology and you can create up to seven custom gamma curves. You
can select any custom or standard gamma curve on a job by job basis
using the front panel Gamma menu or the Print dialog box Gamma PPD
option. See "Dot Gain Calibration (Gamma)" in chapter 6 for details.
Custom curves are created with XANTÉ Command Center and a
densitometer using the following steps:
• Printing a Calibration Page
• Using the Densitometer
• Linearizing the Densitometer Data
Printing a Calibration Page
To begin calibrating your printer, print a calibration page to measure the
printer's current performance as a basis for the calibration.
