The Software: Extensive Calibration Capabilities

Simple and Precise Calibration

The EIZO-developed ColorNavigator software makes calibra- tion both simple and accurate. Instead of having to judge colors and do time-consuming inputting, or having a specialist do it for you, all you need to do is input target values for brightness, white point and gamma. ColorNavigator works with a wide range of measurement devices to directly utilize the 12- or 10-bit LUT of ColorEdge moni- tors for accurate and reliable calibration in minutes.

Preset or User-Assigned Values

Preset Values
Printing and
Photography/Graphic
Design settings are
available with default
values. Just select
either one and Color-

calibrating. Ideal for
users with limited

knowledge, this takes
the guesswork out of
assigning values.

Experienced

and then calibrate.
Calibration Parameters
		30 cd/m2– 200 cd/m2† in 5 cd/m2 increments.
		Setting to the monitor’s minimum and maximum
Brightness		values is also possible.
		0.2 cd/m2 – 3.5 cd/m2 (0.1 cd/m2 increments)
	Black Level‡	Setting to the monitor’s minimum value is also
		possible.
White Point	Color Temperature	4,000 K – 10,000 K in 100 K increments
	Color Coordinates	x Value, y Value
Gamma		1.0 – 2.6 in 0.1 increments and L* ¶

†With the CG222W and CG221, it may not be possible to set the brightness to the maximum value (200 cd/m2) depending on LCD panel performance.

‡With the CG19, choosing 6-Color Adjustment after calibrating will disable the black level adjustment function, and gamma will only be adjustable from 1.8 to 2.6 in increments of 0.2.

Paper White Measurement

ColorNavigator offers a paper white measurement function for color matching between the image on your monitor and the image on your printouts. By measuring the white of the paper to be used for printing, ColorNavigator will automatically set the target values for brightness and white point accordingly.

Profile Validation

This function measures the moni- tor’s color patches to determine the dif- ference between the Delta-E value of the monitor’s profile and the actual displayed values of the moni- tor. This allows for verifying the results

of calibration or checking to see how much the monitor’s colors have varied since it was last calibrated. The measurement results of both the monitor and profile for each color patch are indicated in either CIELAB or XYZ values, and the difference between them expressed in Delta-E. The Delta-E variation can be shown in a graph and com- pared with previous results

Post-Calibration Color Adjustment

Sometimes due to variations in output from different printers or the special requirements of a project, it is necessary to fine-tune an otherwise perfectly calibrated monitor to match target colors. ColorNavigator lets you easily adjust hue and saturation for all

six primary and secondary colors (RGB and CMY), as well as white balance, brightness, black level and gamma, to achieve the closest pos- sible visual match. For confirmation of calibration results or to achieve more accurate manual adjustments, a test pattern screen with a gray- scale ramp, low tones, high tones and gamma values can be displayed.

Recalibration Reminder

After initial calibration, a monitor needs to be recalibrated at

regular intervals to maintain color accuracy. ColorNavigator includes a recalibration reminder that will appear after a certain number of user-determined hours. When the monitor is first calibrated, the date and time are saved. After the time you set has elapsed, an LED on the front panel lights up, and a reminder message appears the next time ColorNavigator starts up. (Not available with the CG19.)
