2-2 Color 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 copier.
• Calibration sets are sets of measurements.
• A calibration target that describes the expected behavior of the copier is contained
in each output profile.
After you have calibrated the Fiery X3e, a calibration set is stored. This calibration set
will be 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
need to reprocess (reRIP) the job. The new calibration affects the job without needing
to be reprocessed.
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 X3e Setup to control access to calibration (see the Configuration
Guide).

Understanding calibration

Although most users' needs are met by the default calibration set, the Fiery X3e 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 X3e.
• Ensure consistent color quality over time.
• Produce consistent output across Fiery X3e servers.
