Introduction
What is EFI Color Verifier?
EFI Color Verifier is a color checker tool. It enables you to
measure and compare two different sets of color values to
ensure that color accuracy is maintained.
The software is extremely flexible and can be used to check
the color accuracy of the following different output
combinations:
• Profile-to-proof
• Proof-to-proof
• Proof-to-print
• Print-to-print
• Profile-to-print
Comparing profile-to-proof is one of the most useful
applications for EFI Color Verifier. For example, in a normal
everyday situation, you can compare the color values of a
proof that has been created on your printer with those of the
profile that simulates the printing press used for the final
print run. If the measured color values are a good match,
this indicates that the final print run will also be color
accurate.
The measured values can be saved, so that the information
can be dispatched easily, e.g. via e-mail, to verify the print
quality. This makes EFI Color Verifier ideal for use in both inhouse as well as in remote environments.
Please be aware that it is not possible to process
grayscale or L*a*b* files in EFI Color Verifier.
DIN ISO support
EFI Color Verifier supports the following latest DIN ISO
norms.
• DIN ISO 12647-7 defines general proofing requirements
for offset printing and all digital printing technologies.
• DIN ISO 12647-2 (second edition) defines the latest
standards for offset printing.
EFI Color Verifier is, therefore, an indispensable tool for:
• achieving Fogra Proof Certification
• creating a DIN ISO 12647-7 compliant proof
You will find practical exercises on how to use the software
for these purposes later in this manual.

Manual conventions
Notes give additional, useful information about
specific topics.
Warnings must be read carefully. They indicate
permanent actions which, once executed, cannot
be undone.
EFI Color Verifier runs on both Windows and Macintosh OS.
With the exception of the uninstall procedures, which are
described separately for each operating system, all the
screen captures illustrated in this manual have been created
from the Windows version of the software.
Therefore, if you are using the Macintosh version of EFI
Color Verifier, you may notice slight differences in the
appearance of your software. However, unless otherwise
stated, the functionality of the user interface is the same for
both operating systems.

Starting your software
To start EFI Color Verifier, double-click the program icon.
An error message may appear if the dongle is not
properly inserted. Insert the dongle and click “OK”.
The first time you start your software, a message informs
you that no license file is installed. Without a license file, EFI
Color Verifier is severely restricted in its functionality and
many of the settings are dimmed. Before you can work with
your software, you must first obtain and install a license file,
as described in the following sections.
Licensing your software
EFI Color Verifier is subject to a complex license
management system, which ensures that upgrading to
future program versions is both easy and convenient.
How does the license management system work?
A so-called "EAC" (Entitlement Access Code) is shipped with
EFI Color Verifier.
In most cases, EFI's license terms will allow you to run your
software on just one computer at a time. To prevent
unlawful copying of the software, EFI uses a hardware copy
protection (dongle). The dongle is a piece of hardware
which has an electronically integrated "dongle ID". Each
dongle is unique and can be identified by its ID.
Before you can use EFI Color Verifier, you must first create a
link between the software you have purchased and the
dongle by generating a “license file”. This is performed at
EFI's Product Activation website.
Where to get the EAC code
Your dealer is responsible for ensuring that you receive all
the necessary items. You will find the EAC code printed on
the Product Activation Certificate. If the Product Activation
Certificate is missing from the scope of delivery, please
contact your dealer for assistance.
How to determine the correct dongle ID
To determine the dongle ID, make sure that the dongle is
connected to a USB port on your computer. Then, from the
“Preferences” menu, choose “License > Show dongle ID”.

Generating a license file
To generate a license file, proceed as follows:
1. Go to the website http://activation.efi.com. The “Login”
dialog opens.
2. Make a language selection to define the display
language.
3. Type the Entitlement Access Code (EAC) printed on the
shipped Product Activation Certificate. Please note that
the EAC code is case-sensitive.
4. Click "Submit" to open the "Entitlement Information"
dialog.
5. Select the check box next to the product for which you
wish to generate a license file.
6. Click “Next” to open the “Host Information” dialog.
7. Type your dongle ID in the text box.
Please note that the dongle ID is NOT the BTxxxxx-xxxx number on the label which may be
attached to the dongle. See page 7 for further
information on how to determine the correct
dongle ID.
License files are generated for a specific
dongle ID. Therefore, it is essential that the
code you type matches exactly the dongle ID. If
you type an incorrect code, the license file will
not be detected when you launch the software.
8. Click "Next" to open the "Confirm Your Selection" dialog.
9. Check the order information and the dongle ID.
10. Click "Generate License" to open the "License(s)" dialog.
11. Specify how you want to receive your license file.
Click "Save to File" to save the generated license file to a
defined location on your computer. The license file is
saved in text format with the file extension *.lic.
Type an e-mail address and click "Send Email" to send
the license file to any e-mail address. A dialog opens to
confirm that the license file has been sent to the
specified e-mail address.
12. Click "Logout" to exit the website.

Installing the license file
Make sure that only the EFI Color Verifier dongle is
plugged into your computer when installing the
license file. If multiple dongles are plugged in, this
can lead to license recognition problems.
To install the license file, proceed as follows:
1. From the “Preferences” menu, choose “License ->
Include new license file”. The “Open” dialog opens.
2. Navigate to the license file, select it and click "Open". The
license file is automatically copied to the folder Program
Files/FlexLM.
You can now use EFI Color Verifier.
The following sections describe the user interface and the
available settings. However, if you prefer to start working
immediately with EFI Color Verifier, you can proceed directly
to “Using EFI Color Verifier” on page 19.
When you install a license file, it is automatically
linked to the computer on which the software is
installed. The link is created by adding the
computer name to the information stored in the
license file. Therefore, please be aware that if you
change the computer name EFI Color Verifier will
no longer recognize the license file. To remedy the
problem, reinstall the license file.

patch is printed out automatically with your
print job.
However, if you have selected an Ugra/Fogra
media wedge, you will need to print the TID
patch separately. The file “-TIDforMKV20XPV2.tif” is provided for this purpose. You will
find it in the “Tools” folder.

Analyzing the results
Once you have obtained M1 and M2 values, the results are
evaluated and can be viewed:
• In the “Results” area of EFI Color Verifier
• By printing a protocol/label
Viewing the results in EFI Color Verifier
The "Results" tab contains a summary of the overall result. If
any of the measurements lie outside the specified range of
tolerance, EFI Color Verifier indicates a result of “Not
passed”.
A check mark indicates that the overall measurement is
within the tolerance limit. A cross warns you if some or all
the measurements exceeded the maximum tolerance
values.
The tabs “Delta E” and “Delta H” contain a detailed
breakdown of the results and show you if any
measurements were unsatisfactory for the primary colors.
In the example, the “Results” tab shows that not all the
maximum peak delta E values are within the tolerance
limits. By clicking on the “Delta E” tab you can see that it is
the values for Yellow and Black that are out of range and,
therefore, the cause of the overall result “Not passed”.
The number of displayed tabs changes, depending
on the setting you made in the “Preferences”
dialog.
• If you selected “ISO 12647-7 Contract Proof
Media Wedge”, results are displayed for delta E
and delta H.
• Measuring against the “ISO 12647-7 Contract
Proof Chart” displays results for delta E and
delta T.
• If you selected “Custom”, the “Results” area
displays tabs for delta E, delta H and delta T.
Printing a protocol
To output a protocol with details of the reference and
measured data, select the appropriate command from the
File -> Print menu.
The final page of the protocol shows CMYK gradation curve
diagrams, depicting all reference and measured points
along the curve.

Glossary
This glossary gives a brief explanation of the terms used in
this manual.
C
Color temperature of 6,774 Kelvin which corresponds to
daylight.
CIE 94
A tolerancing system utilizing three-dimensional
ellipsoids as containers for color acceptance. CIE 94 is
similar to CMC but lacks some of the hue lightness
adjustments. CIE 94 colors have 95% agreement with
color differences as our eyes see them. CIE 94 is used
predominantly in the paint and coatings industry.
CIELAB
A color model based on the model proposed by the
Commission Internationale d'Eclairage (CIE) in 1931 as
an international standard for color measurement. In
1976, this model was refined and named CIELAB. L*a*b*
color is designed to be device-independent and
perceptually uniform. L*a*b* color consists of a
luminance or lightness component (L*) and two
chromatic components: the a* component (from green to
red) and the b* component (from blue to yellow).
CIELCH
A color space similar to CIELAB, which uses cylindrical
coordinates of lightness, chroma, and hue angle instead
of rectangular coordinates.
CMC
A tolerancing system based on CIELCH. It portrays colors
as three-dimensional ellipsoids and represents colors as
they are interpreted by the human eye. CMC colors have
95% agreement with color differences as our eyes see
them. CMC is used predominantly in the textile industry.
CSV
A file format for saving color measurement results in EFI
Color Verifier. A csv file can also be opened and edited in
any spreadsheet application.
D50
Color temperature of 5,000 Kelvin used for color
matching in the photographic industry and in the printing
industry. D50 is used predominantly in Europe.
D65
Color temperature of 6,504 Kelvin used for color
matching in the printing industry. D65 is used
predominantly in the USA.
EFI Color Verifier 3.1.2
User Manual
31
Delta E
The mathematically calculated distance in the CIE L*a*b*
color space between two colors. Delta E is used to check
total color tolerances in a color-management
environment.
Delta H
The difference in hue. In a color wheel, hue is defined by
the angle between two colors.
See Hue
Delta T
The amount of dot gain, i.e. increase in the size of inkjet
droplets when compared to the simulation profile.
Dot gain
See tone value
Gamma
The ratio of the contrast range between original and
reproduction. A gamma value of 1 means that the
original and copy proof have the same contrast range.
Hue
The dominant wavelength of a color. A color system, or
model, measures color by hue, saturation and
luminance. The hue is the predominant color, such as
yellow or green, the saturation is the color intensity, and
the luminance is the brightness.
JDF
Job Definition Format. A file format used in the graphics
industry to standardize communication between the
individual pre-press, print and further processing stages.
The jdf file contains all the settings made in an EFI Best
product that affect color reproduction, including print
resolution and print medium.

PDF
Portable Document Format. A method of formatting
documents in such a way that they can be viewed and
printed on multiple platforms using the freely available
Adobe Acrobat Reader™.
RGB
The additive color system used in digital cameras and
computer monitors where red, green, and blue light is
captured separately and then combined to create a full
color image.
Tone value
The amount that an ink halftone dot expands when
applied to the surface of a paper, causing darker tones or
stronger colors. This is usually a factor of the type of
press and the absorbency of the paper.
For example, screen printing increases density by about
15%, so an image with a 50% black fill would appear as
approximately 65% black after printing.
XYZ
A device-independent color model developed by CIE
(Commission Internationale de l'Eclairage), in which RGB
values are mathematically transformed into a system
that uses x, y and z as coordinates. While x and z values
have no specific perceptual correlation, the y value
represents brightness (luminance).
