Calibration adjusts the ink or toner densities of a job to compensate for the difference between the expected (target) densities of the printer and the actual (measured) densities that the printer outputs.

Calibration
Calibrating the C9 Server ensures consistent and reliable color output. Calibration adjusts the ink or toner densities
of a job to compensate for the difference between the expected (target) densities of the printer and the actual
(measured) densities that the printer outputs.
Periodic calibration is necessary to monitor the actual output of the printer. To calibrate the C9 Server, you measure
the densities of printed color patches on a page.
Calibration is applied to all jobs, but you can disable it for a specific job. The ColorWise Off setting for the CMYK/
Grayscale Source option disables calibration (and color management) for CMYK data in a job. You might want to
disable calibration for testing purposes, for example.
If you defined a custom halftone screen with the Halftone Simulation feature, you must calibrate the C9 Server for
that halftone screen before you print a job with it.
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 to control access to calibration (see
Configuration
and Setup
).
Check calibration status
You can check when the C9 Server was last calibrated in Command WorkStation.
Check the calibration status for a job
•
In Command WorkStation, in Job Center, select the job.
The time of the most recent calibration is displayed in the lower-right corner.
Check the status of a specific calibration
1
In Command WorkStation, in Device Center, click the
General
tab, click
Tools
, and then click
Manage
(under
Calibrate
).
The list of calibration settings on the C9 Server appears in Calibrator.

Find the calibration in the list and check the
Last calibrated
value.

indicates the factory settings, which means that the C9 Server has not been calibrated.
You can configure Command WorkStation to optionally display a warning or suspend printing if the calibration
of a job is out of date. For more information, see the online help.
