2-1 Color Calibration
Chapter 2:
Color Calibration
Calibrating the EX7750 ensures consistent, reliable color output. This chapter explains
how calibration works and provides instructions for all calibration procedures.
This chapter describes calibrating the EX7750. You must also calibrate the
N :
OTE
Phaser 7750. For instructions, see the documentation that accompanies your printer.
We recommend that you calibrate the Phaser 7750 first, and then the EX7750.
Calibrate the EX7750 using ColorWise Pro Tools in combination with any of the
following color measurement instruments:
• EFI Spectrometer ES-1000 hand-held spectrometer
• X-Rite DTP41 automatic scanning spectrophotometer
• X-Rite DTP32 or DTP32HS automatic scanning densitometer
By connecting one of these instruments to a serial or USB port on your computer, you
can quickly measure calibration color patches and download measurements to the
EX7750.
To use the ES-1000 with a Mac OS computer, you must connect the instrument
N :
OTE
to a USB port. For more information, contact your service technician/representative.
For information about setting up and operating the DTP41 and DTP32, see
Appendix A.
Another calibration method, VisualCal
the EX7750. Calibrating from the Control Panel with VisualCal is described on
page 2-20.
When choosing a calibration method, keep in mind that methods using a color
measurement instrument such as the ES-1000, DTP41, or DTP32/DTP32HS are
generally the best. We recommend using the ES-1000 because it captures
measurements very accurately and quickly, can be used to calibrate and profile printers
using pages with randomized patches, and can be used to measure and adjust
individual spot colors.
