The XD-1 (XANTÉ densitometer), combined with XANTÉ Advanced Graphics
Center software, measures grayscale output for calibration and proofing. This
affordable, easy-to-use densitometer will be referenced in this manual for
example
purposes only.
8. 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. 3.171). The measurement appears in
the box to the right of the Measure button.
9. 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 section 3 of the
Densitometer Data Entry window.
For example, when you are reading for 2%, if the box labeled 7 measures 2%,
enter the number 7 in the corresponding box.
The calibration page blocks are numbered from 0 to 255. You may have to check
several blocks to find the one that most closely matches the percentage in the
Densitometer Data Entry window
