Using a spectrophotometer

ColorWise Pro Tools Calibrator is designed to work with 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 3850C automatically.
