ColorNavigator Software
Simple and Precise
Calibration
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 12-bit LUT for
accurate and reliable calibration in minutes.
Paper White Measurement
ColorNavigator offers a paper white
measurement function for color
matching between the image on the
monitor and the im-age on the print-
outs. By measuring the white of the
paper to be used for printing, Color-
Navigator will automatically set the
target values for brightness and white
point accordingly.
This function is compatible with the X-Rite DTP94,
DTP94B, Eye-One Display 2, and Eye-One Pro only.
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 colors
(red, green, blue, cyan, magenta and yel-
low), as well as white balance, brightness,
black level and gamma, to achieve the closest
possible visual match. For confirmation of
calibration results or to achieve more accu-
rate manual
adjustments,
a test pattern screen can now be dis-
played. The test pattern screen shows a
full grayscale ramp as well as just the
low tones (blacks), high tones (whites),
and gamma values. The results of all
manual adjustments are immediately
reflected on the test pattern screen.
Convenient Calibration Profile Management
ColorNavigator also makes it
easy to keep track of calibra-
tion proles. When you want
to adjust a profile in order to
match your monitor to other
equipment such as printers or
light boxes, 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 recalibra-
tion 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 difference (Delta-E) between the
original target points and the actual current points at any time.
