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.)

Calibration Parameters
Brightness
30 cd/m 2 – 200 cd/m 2† in 5 cd/m 2 increments.
Setting to the monitor’s minimum and maximum
values is also possible.
Black Level‡
0.2 cd/m 2 – 3.5 cd/m 2 (0.1 cd/m 2 increments)
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/m 2 ) 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.
