Scheduling calibration
Calibrate the Fiery EX8000AP at least once a day, depending on the volume of print jobs.
If it is very important to maintain consistent color, or your digital press 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 or printing results are not as
expected.

If you must split a print job into two or more batches to print at different times, it is
important to calibrate before you print each batch. You should also calibrate the Fiery
EX8000AP after digital press maintenance. However, because the digital press may be less
stable immediately after maintenance, wait until you have printed approximately 50 pages
before you calibrate.

Because printed output from the digital press is very sensitive to changes in
temperature and humidity, do not install the digital press near a window, in direct sunlight, or
near a heater or air conditioner. Paper is also sensitive to climate changes. Store it in a cool,
dry, stable environment, and keep reams sealed until they are used.

To monitor print quality, print the following color pages:
• Color Charts (from Command WorkStation)
• Color reference pages included in the User Software DVD (see pages
These pages include fully saturated color patches and pale tints of cyan, magenta, yellow,
and black. Images with skin tones offer a good basis for comparison. Save and periodically
compare the pages you print. If a noticeable change in appearance occurs, calibrate the Fiery
EX8000AP.
and black. Images with skin tones offer a good basis for comparison. Save and periodically
compare the pages you print. If a noticeable change in appearance occurs, calibrate the Fiery
EX8000AP.
When you examine the Test Page, all color patches should be visible, even though they may be
very faint in the five to two percent range. Each patch set should show uniform gradation
from patch to patch as the color lightens from 100% to zero.

from patch to patch as the color lightens from 100% to zero.
If the solid density patches (100% cyan, magenta, yellow, or black) look less saturated over
time, show the pages to your digital press service technician to determine whether adjusting
the digital press can improve output.

Checking calibration status
To verify whether the Fiery EX8000AP is calibrated, which calibration set and output profile
were used, and when the digital press was last calibrated, perform the following:

• Print a Configuration page or Test Page from Command WorkStation.
• Select a calibration set in Calibrator. The last calibration and the user who performed it
are displayed.
