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-

Navigator will begin

calibrating. Ideal for

users with limited

color management

knowledge, this takes

the guesswork out of

assigning values.

User-Assigned

Values

Experienced

users can assign the

desired values for

brightness, white

point, and gamma

and then calibrate.

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.

Proﬁ le Validation

This function

measures the moni-

tor’s color patches to

determine the dif-

ference between the

Delta-E value of the

monitor’s proﬁ le 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 proﬁ le 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 ﬁ ne-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 conﬁ rmation 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 ﬁ rst 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.)

increments.

Setting to the monitor’s minimum and maximum

values is also possible.

Black Level‡

increments)

Setting to the monitor’s minimum value is also

possible.

† With the CG222W and CG221, it may not be possible to set the brightness to the maximum value (200 cd/m

) 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.
