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 copier.
•
Calibration sets are sets of measurements that represent the output of specific
combinations of media-related options.
•
Each output profile contains a calibration target that describes the expected behavior of the
copier.
After you calibrate the E100, 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.
How calibration works
Although the needs of most users are met by the default calibration set, the E100 allows you
to choose a calibration set to customize calibration for specialized jobs.
Calibration allows you to:
•
Maximize the color reproduction capabilities of the E100.
•
Ensure consistent color quality over time.
•
Produce consistent output across E100 servers.
•
Achieve better color matches when reproducing
spot colors
, such as PANTONE colors or
other
named color
systems.
•
Optimize the E100 for using ColorWise rendering intents, CMYK simulations, and ICC
profiles.
Success in obtaining satisfactory print quality from the E100 depends on many factors.
Among the most important are establishing and maintaining optimal toner densities. The
density
is the measure of the light absorbed by a surface. By carefully regulating toner
densities, you obtain consistent printed color.
