Adjusting monitor display conditions
After ambient light has been adjusted, it’s time to calibrate the monitor to match the lighting situation. Use the ColorNavigator or ColorNavigator CE calibration software included with ColorEdge monitors for simple, quick, and accurate calibrations. In addition, a sensor is required for calibration. ColorNavigator and ColorNavigator CE supports the following sensors:
•
X-Rite Eye-One series
• Monaco OPTIX XR series
• ColorVision Spyder 2 series
Typical calibration software is provided with these sensors. However, we recommend using only ColorNavigator or ColorNavigator CE to calibrate your ColorEdge series monitor.
When visually matching a monitor and photographic print, the white point and brightness of the monitor needs to be matched to the photographic paper that will actually be printed. Place the paper where you can compare it to the monitor, then match the two with respect to white point and brightness as explained below.
With ColorNavigator and ColorNavigator CE, calibrations are performed for White Point, Brightness, and Gamma.
Calibration points
[1] White Point
As previously noted, the monitor’s whiteness should be set as close as possible to the color of the photographic paper used for printing.
White sheets of photographic paper can be measured directly with the DTP94 sensor (included with the MonacoOPTIX XR package) and Eye-One series sensors. This allows more accurate calibration of monitor whiteness and brightness by including ambient light and paper whiteness.
If another sensor is used, find the color temperature of the fluorescent lamp used (e.g., 5,000 K), and set ColorNavigator or ColorNavigator CE to this value. If the whiteness of the monitor appears slightly blue after calibration, lower the white point color temperature, then recalibrate. Some of the Eye-One series provides ambient light-measuring functionality, a feature supported by ColorNavigator and ColorNavigator CE. If you use this combination, click the [Measure the target] button to measure ambient light. The measurement value will be set as x,y coordinate values for the white point target.
[2] Brightness (when not using DTP94 or Eye-One series sensors)
If you are not using the DTP94 or Eye-One series, you will have to set the brightness value. (Adjusting the brightness is not necessary when using the white point measuring function described in section [1].) With a typical monitor, the brightness of photographic paper when viewed at night under artificial illumination corresponds to about 80 to 100 cd/m2. Naturally, brightness will vary with the number of fluorescent lamps and distance to the paper. At first, try to calibrate to 100 cd/m2. If the monitor appears brighter than the paper, lower the brightness settings and recalibrate.
[3] Gamma Value
Set the gamma value to 2.2, regardless of whether the PC used is Macintosh or Windows.
