Understanding calibration
The following sections describe important concepts and suggestions for understanding
calibration.
An overview of calibration
Calibration generates curves that adjust for the difference between the actual toner densities
(measurements) and the response expected by the output profile.
•Measurements represent the actual color behavior of the digital press.
• Calibration sets are sets of measurements that combine media and screen options provided
for Calibrator.
• Each output profile contains a calibration target that describes the expected behavior of the
digital press.
After you calibrate the Fiery EXP8000/50, a calibration set is stored. This calibration set is
used when it is associated with an output profile. Every output profile has an associated
calibration set. If you have not specified one, the calibration set associated with the default
output profile is used.
If you change the calibration after a saved job has been processed (RIPped), you do not have
to reprocess (reRIP) the job. The new calibration affects the job without reprocessing.
NOTE: Changing calibration has the potential to affect all jobs for all users, so consider
limiting the number of people authorized to perform calibration. Set an Administrator
password in Fiery EXP8000/50 Setup to control access to calibration (see Configuration and
Setup).
How calibration works
Although the needs of most users are met by the default calibration set, the Fiery EXP8000/
50 allows you to choose a calibration set to customize calibration for specialized jobs.
Calibration allows you to:
•Maximize the color reproduction capabilities of the Fiery EXP8000/50.
•Ensure consistent color quality over time.
•Produce consistent output across Fiery EXP8000/50 servers.
•Achieve better color matches when reproducing spot colors, such as PANTONE colors or
other named color systems.
•Optimize the Fiery EXP8000/50 for using ColorWise rendering styles (CRDs), CMYK
simulations, and ICC profiles.
