e. Click Print Calibration Page (fig. 3.15). The calibration
page shows the printer’s performance using no gamma
curve correction (fig. 3.16).
Note: Print only one calibration page (using the Print
Calibration Page button) at the beginning of the
calibration process. Printing this page again later
in the process resets the calibration, cancelling
any linearization you have already done.

Using the Densitometer
A densitometer uses a standard light source to measure the amount of
light reflected from printer output. This measurement is compared to
a standard and expressed as a percentage of gray.
The densitometer, like any other precision instrument, must be
calibrated before each use. Refer to your densitometer’s
documentation for instructions on calibrating and using the
densitometer.
