ColorNavigator Software

Unmatched Calibration

Capabilities

The EIZO-developed Color- Navigator software makes calibration both simple and accurate. Instead of having to judge colors and do time-con- suming 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 directly utilizes the 10-bit Look-Up Table and automatically calibrates the monitor in less than 10 min- utes. The ColorEdge CG220 incorporates the latest generation of this software, which gives you a number of other useful functions, some of which are as follows.

Calibration Parameters

		30 cd/m² – 200 cd/m²* (5 cd/m² increments)
Brightness		Possible to set to the monitor’s maximum and minimum values.
	Black Level	0.5 cd/m² – 3.5 cd/m² (0.1 cd/m² increments)
		Possible to set to the monitor’s minimum value.
White Point	Color Temperature	4000 K – 10000 K (100 K increments)
	Color Coordinates	X Value, Y Value

* Depending on LCD panel performance, it may not be possible to set the brightness to the maximum value (200 cd/m2).

Post-Calibration Color

Adjustment

Sometimes due to variations in out- put 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. Color- Navigator lets you easily adjust hue and saturation for all six colors (red, green, blue, cyan, magenta and yellow), as well as white balance, brightness, black level and gamma, to achieve the closest possible visual match.

Color Profile Generation

ColorNavigator can save up to 20 different calibration profiles. Any of these can be used for setting the monitor or for generating a ColorSync or ICM color profile for the computer’s operating system. For example, if you use one monitor for both web design and printing, you can save a different calibration profile for each task, then call up each profile as you need it.

Convenient Calibration Profile Management

ColorNavigator also makes it easy to keep track of calibration profiles. When you want to adjust a profile in order to match your monitor to other equipment such as print- ers or lightboxes, you can use the Duplicate function to make a copy of it, then adjust the duplicate profile

and give it a new name. Naturally, you can make as many duplicates, and thus adjusted profiles, as desired.

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. If you prefer to calibrate according to the amount of change that has occurred, you can measure the color differ- ence (Delta-E) between the original target points and the actual current points at any time.

0.5 Delta-E Difference

The combination of the monitor’s 10-bit look-up table, Color-

Navigator software, and a calibration device (see page 12 for details) produces extremely accurate colors with a very low Delta-E difference of less than 0.5.

*Delta-E is the color difference between the target white point and the monitor’s white point.
