Color Measurement Instruments

C9800 Color Guide - 84

This appendix explains how to set up and calibrate the following color measurement 
instruments:

• X-Rite DTP41 automatic scanning spectrophotometer

• X-Rite DTP32 automatic scanning densitometer

Using the X-Rite DTP41 spectrophotometer

ColorWise Pro Tools Calibrator supports the X-Rite DTP41 spectrophotometer, a 
device that measures density and color data. The DTP41 communicates directly with 
the Calibrator application in ColorWise Pro Tools, sending measurements to the Fiery 
automatically.

Setting up the DTP41

Before you calibrate the Fiery, you must connect, configure, and calibrate the 
spectrophotometer to prepare for measuring the printed patches. For additional 
information about setting up and using the DTP41, see the documentation included 
with the instrument.
