Introduction
Calibrating the Fiery 3850C ensures consistent, reliable color output. You can calibrate
the Fiery 3850C with ColorWise Pro Tools using any of these instruments:
• X-Rite DTP41 automatic scanning spectrophotometer (page 3-7)
• X-Rite DTP32 automatic scanning densitometer (page 3-25)
• EFI ED-100 Densitometer (page 3-25)
Each of these instruments must be purchased separately. By connecting the instrument
to the serial port on your computer, you can quickly measure color patches and
download measurements to the Fiery 3850C. You can also obtain measurements from
the printer’s built-in scanner and calibrate using VisualCal, which does not require the
use of a densitometer and can be run from ColorWise Pro Tools. VisualCal is run from
the Control Panel on the Fiery 3850C.
This chapter explains how calibration works and provides instructions for all
calibration procedures. Calibrating with VisualCal is described onpage 3-5.
Calibrating with ColorWise Pro Tools is described on page 3-29. For information on
advanced calibration and simulation features such as editing profiles and creating
custom profiles, see Chapter 4. A format for inputting color measurements from other
densitometers is described in Appendix C.
The procedures described in Chapters 3 and 4 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 densitometer.
Introduction
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.
• A calibration target that describes the expected behavior of the printer is contained
in each output profile.
