2-36 Color Calibration
C9800 Color Guide - 36
Measurements
Measurement files contain numerical values that correspond to the toner density
produced by the printer 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 a color measurement instrument connected to a computer on the network. 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
page 1-26 .
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 printer 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 printer maintenance.

:
Because printed output from the printer is very sensitive to changes in
temperature and humidity, the C9800 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.
