Color Calibration
Measurements
Measurement files contain numerical values that correspond to the toner density
produced by the copier when it prints solid cyan, magenta, yellow, and black, and
graduated tints of those colors.
To create a measurement file, print a page of color patches. Then measure the patches
using either a color measurement instrument connected to a computer on the network
or, if it is available, the print device’s scanner. The new measurements are automatically
downloaded to the Fiery.
Output profiles and calibration sets
Output profiles and calibration sets define desired calibration results. One or more
output profiles and calibration sets are provided with the Fiery. When you calibrate the
Fiery, select the calibration set that corresponds to the typical printing jobs at your site.
This same calibration set can be associated with one or more output profiles. For more
information on output profiles, see
.
Scheduling calibration
In general, you should calibrate the Fiery at least once a day, depending on the
volume of print jobs. If it is very important to maintain consistent color, or if the
copier is subject to wide fluctuations in temperature or humidity, calibrate every few
hours. For optimal performance, calibrate whenever there is a noticeable change in
print quality.
If you need to split a print job into two or more batches to be printed at different
times, it is especially important to calibrate before printing each batch. You should
also calibrate the Fiery after copier maintenance. However, because the copier may be
less stable immediately after maintenance, wait until you have printed approximately
50 pages before you calibrate.

Because printed output from the copier is very sensitive to changes in
temperature and humidity, the copier should
not
be installed near a window or in
direct sunlight, or near a heater or air conditioner. Paper is sensitive to climate changes
as well. It should be stored in a cool, dry, stable environment, and reams should remain
sealed until they are needed.
