Choosing the right monitors for a
color management system
The Importance of Color Management
In today’s digital production environment, there
are many opportunities for discrepancies in color to
arise along the path from the computer to the printer.
This is because input devices (cameras, scanners, etc.),
display devices (monitors) and output devices (various
kinds of printers) may all be set to different color
spaces. Such discrepancies can be avoided by employing a color
management system that ensures every device in the production
chain is set to a common color space.
reliabilit y make them ideal for a wide range of professiona l
environ ments where color reproduction is critical, includ ing
photography, graphics, printing and publishing.
Color Management Begins with
the Monitor
The monitor is the core of any professional color
management system. If color is displayed accurately on
the monitor, and color matching has been done with
the output device, then you no longer have to make
multiple proofs just to correct for color discrepancies.
You can proof with confidence rig ht from the star t,
while lowering costs, increasing efficiency and
improving quality control.
ColorEdge – the Right Monitors for
Color Management
Effective color management requires monitors
with accurate color reproduction and gradation
characteristics. With ColorEdge monitors you
get factory-adjusted gamma, extensive hardware
calibration capabilities and an exceptionally wide
color gamut. Their outstanding performance and

Soft Proofing with Adobe RGB
The benefits of color management quickly become apparent
once a system is put into place. When all devices share a
common color space, colors match at every stage of production;
knowing that color is being accurately displayed naturally
improves efficiency. A wide-gamut ColorEdge monitor at the
center of a system using Adobe RGB as the common color space
is the ideal way to ensure accurate color reproduction across all
digital platforms. Such a color management environ ment fully
supports soft proofing at every step of production, from initial
photography to final printing.
With a wide color gamut
that reproduces nearly 100%
of the Adobe RGB color space,
these models not
only cover the
sRGB color space
suppor ted by many
computer monitors,
operating systems
and digital cameras,
but practically the
entire ISO-coated
and US web-coated CM YK color spaces used in
printing as well.

The gamma level for
each ColorEdge monitor
is adjusted at the factory.
This is accomplished by
measuring the R, G, and
B gamma values from
0 – 255, then using the
monitor’s 12-bit look-up
table (LUT) to select the
256 most appropriate
tones to achieve the
desired value.
This is important
because accurate, nonfluctuating ga mma
values are necessary for
the proper display of
color. If colors are not
based on specific values
and cannot be adjusted,
images will be displayed
differently by different
monitors. ColorEdge
monitors provide both
precision and consistenc y, so graphic s
professionals can be sure
that the final product
will look exactly the way
they want it to. In fact,
each mon itor comes with
an adjustment certificate
that certifies the measurement results of the
gamma value.
Each monitor adjusted individually at the
factory. (For illustrative purposes only. Actual
adjustment is performed in a darkroom.)
Brightness and Color Uniformity with DUE
Fluctuations in brightness and chroma on different parts of the
screen are a common trait of LCD monitors. To counteract this,
EIZO incorporates a Digital Uniformity Equalizer (DUE) in all ColorEdge monitors. DUE utilizes the monitor’s 12-bit look-up table
(LUT) with an extensive palette of 4,081 grayscale tones for each
R, G, and B, and internal calculation accuracy of 16 bits to ensure
a Delta-E difference of 3 or less across the screen when the monitor
leaves the factory.*

Short- and Long-Term Brightness Stabilization
All models come with a brightness drift correction circuit that
stabilizes the monitor's brightness level right after starting up as
well as a backlight brightness sensor that detects and counteracts
brightness changes in the florescent backlight that occur over time.
Furthermore, the CG245W, CG243W, and CG223W incorporate
a temperature sensor that prevents changes in color temperature
which can be caused by fluctuations in the ambient temperature.

16-Bit Internal Processing
In any color-critical work, the monitor’s ability to produce black is a great differentiator. With most LCD
monitors, the darkest area of the screen — or black
level — is usually too bright. This leads to banding and washing
out of dark grays and dark colors. With 16-bit internal processing,
ColorEdge monitors not only come very close to producing a true
black, but the lowest grayscale tones can be distinguished from one
another for a greater level of detail in dark areas.
16-bit v. 10-bit processing
With 10-bit processing, the error rate is high in low tonal areas during calculation. With 16-bit processing, accuracy is significantly improved resulting in
fewer conversion errors.
3D LUT for Better Additive Color Mixture
All ColorEdge models
incorporate a look-up table
(LUT) for accurate color
and grayscale rendering, but
the ColorEdge CG245W,
CG243W, and CG223W utilize a new EIZO-developed
3D LUT. Whereas a typical
1D LUT adjusts color on
separate tables for each red,
green, and blue, a 3D LU T
accomplishes this on a single, mixed-color cubic table. A 3D LUT
improves the monitor's additive color mixture (combination of
RGB), a key factor in its ability to display neutral gray tones.

Extensive Calibration Capabilities
Simple and Precise Calibration
The EIZO-developed ColorNavigator
software makes
calibration both
simple and accurate. Instead of
having to judge
colors and do
time- consum ing
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 di rectly utilize the 12-bit LUT
of ColorE dge monitors for accurate a nd reliable calibration in
minutes. The latest version of ColorNavigator is always available
as a free download at www.eizo.com.
Industry’s First Self-Calibrating Monitor
The ColorE dge CG245 W
comes with an industry-first
bui lt-in calibration sensor.
The sensor is housed within
the monitor’s upper bezel and
swings down only when operati ng. This eliminates the need
for an external sensor, le ts you cal ibrate when you r computer
is off, and saves time by lett ing you schedule the monitor to
self-calibrate while you are not working. To ensure predictable
and accurate calibration across the screen, EIZO calibrates the
center of the screen at its factory and correlates the built-in sensor to these results. Furthermore, if you are working w ith other
ColorEdge mon itors a nd need to standard ize calibration, you
can use the bundled ColorNavigator soft ware to correlate the
calibration results of the built-in sensor to the results obta ined
from an ex terna l calibration devic e.
Paper White Measurement
ColorNavigator offers
a paper white measurement
function for color matching between the image
on your mon itor and the
image on your printouts. By
mea suring the white of the
paper to be used for printing, ColorNavigator will
automatically se t the target
values for bright ness a nd
white point accordingly.
Light Box Brightness Adjustment
With ColorNavigator and a measurement device, you can set
your light box’s* brightness to the desired value. ColorNavigator
can then take the resulting brightness level and set it as the monitor’s target calibration value to ensure uniform brightness between
your monitor and light box when color proofing.
*Cur rently supports JU ST Color Communi cator 1 and 2 only.
Profile Validation
This function
measures the monitor’s color patches
to determine the difference between the
Delta-E value of the
monitor’s profile and
the actual displayed
values of the monitor.
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.
ColorNavigator can also measure CMYK color patches (GR ACoL
2006 Coated #1 and FOGRA39) and output them as Adobe Photoshop
or Acrobat files.* 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 compared with previous results.
ColorNavigator even exports profile validation results as a PDF for easy
distribution among work sites, printers, or clients.
*Photoshop CS/CS 2/C S3/ CS4 or Acrobat 7/8/ 9 Professional are required for Ma cintosh, and Photoshop C S3 or Acrobat 8 /9 Profession al are required for Windows.
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 possible visual
match. For confirmation of calibration results or to achieve more
accurate manual adjustments, a test pattern screen with a grayscale
ramp, low tones, high tones and gamma values can be displayed.
