3-2 Color Calibration
• A calibration target that describes the expected behavior of the
copier/printer is contained in each output profile.
Once you have calibrated the iR C2100/2100S, a calibration set is stored on
the iR C2100/2100S. 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.
Changing calibration has the potential to affect all jobs for all users, so

you may want to limit the number of people authorized to perform
calibration. An Administrator password can be set from the iR C2100/2100S
Control Panel or in Setup from the Command WorkStation to control access
to calibration.

Understanding calibration

Although most users' needs are met by the default calibration set, the
iR C2100/2100S allows you to choose a calibration set to customize
calibration for specialized jobs.
Calibration allows you to:
• Maximize the color reproduction capabilities of the iR C2100/2100S
• Ensure consistent color quality over time
• Produce consistent output across iR C2100/2100S servers that are
connected to the same print engine
• Achieve better color matches when reproducing spot colors such as
PANTONE colors or other named color systems
• Optimize the iR C2100/2100S for using ColorWise rendering styles
(CRDs) and CMYK simulations, and for using ICC profiles

How calibration works

Success in obtaining satisfactory print quality from a color server such as a
iR C2100/2100S connected to a copier/printer depends on many factors.
Among the most important are establishing and maintaining optimal toner
densities. Density is a measure of the light absorbed by a surface. By carefully
regulating toner densities, you can obtain consistent printed color.
