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.

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
