2-2 Color Calibration
For information about the advanced calibration and simulation features available
with ColorWise Pro Tools, such as editing profiles and creating custom profiles, see
Chapter 3 . A format for inputting color measurements from other densitometers is
described in Appendix B .

The procedures described in this chapter are fundamentally the same for
Windows and Mac OS computers. The main differences are the interface cable and the
port used to connect to the measurement instrument. The illustrations in this chapter
describe the Windows version.

The term “computer” is used to refer to any computer running
ColorWise Pro Tools.
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 printer.
• Calibration sets are sets of measurements.
• Each output profile contains a calibration target that describes the expected behavior
of the printer.
After you calibrate the EX7750, 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
need to reprocess (reRIP) the job. The new calibration settings are in effect for the job.

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 EX7750 Setup to control access to calibration (see the
Configuration
Guide ).
