After calibrating the densitometer, use it to get density measurements
for the calibration page you printed.

Linearizing the Densitometer Data

Enter the densitometer measurements to calculate the adjustments
necessary to correct printer performance to a linear standard.
1. Click Enter Curve/Linearize in the Linearization window (fig.

2. Measure individual patches on the calibration page by placing
the page on a white background; then, center the
densitometer's lens over the patch and either click the black
button on top of the XD-1 or click the measure button on the
Densitometer Data Entry window (fig. 3.17). The
measurement appears in the box to the right of the Measure
button.
3. Make sure to enter the solid black (1) and solid white (2)
measurements first. Enter the number of the patch whose
densitometer measurement most closely matches (within
2%) the corresponding percentage in the Enter Coverage
Values section.
