Ugra/FOGRA Media Wedge v2.2
Verifying FOGRA Validation Print Creation
Professional Printing Solutions
Ugra and FOGRA are organizations well known for their efforts in standardization and
quality control. Together, they have developed the Ugra/FOGRA Media Wedge CMYK v2.2,
a control device used worldwide to evaluate hard copy proofs. When the Ugra/FOGRA
Media Wedge is printed alongside a job, the user is provided a means to measure the
accuracy and consistency of a printer for any printing condition, whether CMYK simulation
or device CMYK color.
Step 1 — Calibrating and Profiling the Fiery driven printer
This document concerns the verification of the FOGRA Validation
of a FIERY Driven printer using the tools contained within the
Fiery Graphic Arts Package, Premium Edition and EFI Color Profiler
Suite. It is assumed that the Fiery driven printer has been Profiled
and Calibrated prior to conducting the verification steps.
Step 2 — Printing with the FOGRA Media Wedge
There are two ways to add the FOGRA Media Wedge control
bar to a document. The first is to place the Ugra Fogra-
MediaWedgeV2.2x_EFIv1.EPS onto a document using the original
application such as Quark XPress or Adobe InDesign. The second
is to use the Control Bar feature on the Fiery with the Graphic
Arts Package Premium Edition installed.
The Control Bar can be accessed by opening ColorWize Pro Tools,
selecting Color Setup and selecting Control Bar. Next select the
Default control bar and choose Edit. Enter a description to identify
the use of the FOGRA Media Wedge and select Browse to locate
the Ugra Fogra-MediaWedgeV2.2x_EFIv1.EPS file. Selecting
“Print Control Bar” in the Control Bar pane will ensure the FOGRA
Media Wedge is printed on every document. Alternatively the
FOGRA Media Wedge can be printed on a per job basis by
turning on the Control Bar in the Job Info pane in the Driver
or Job Properties.
Step 3 — Configuring Preferences in Verifier in
Color Profiler Suite
When validating the FOGRA Media Wedge it is necessary to
configure a few preferences, the first is to identify the device
used to make the measurements. From “Preferences” select
“Measuring Device/Control Strip” -> “Eye One” -> “Ugra
Fogra-Media Wedge 2.2a”.

Step 4 — Configuring Tolerances in Verifier
For verifying a contract proof using the FOGRA Media Wedge
it is necessary for the measurements to be within certain
tolerance limits. Within Verifier these industry standard pre-sets
can be select within the “Preferences” dialog box. From the
“Delta E Tolerance limits” drop down menu select “ISO 12647-7
Contract Proof Media Wedge”. Here you will see that the delta
E, delta H (hue) and delta T (tone) tolerances are populated as
specified for ISO 12647-7 (digital proofing).
Step 5 — Loading the Reference Data
Next step is to identify the FOGRA characterization data set to
which the measurements are evaluated. For Measurement 1
select “Open” and choose a data set, e.g. Fogra39.it8 (for ISO
coated v2 eci) from the “IT8_CharacterizationData/Fogra_
MKCheck10” folder. For other data sets reference the read me
file in the IT8_CharacterizationData folder.
Step 6 — Measuring the FOGRA Media Wedge
For a validated proof, the FOGRA Media Wedge measured must
be that contained on the same printout at the proof. To get started
ensure the ES-1000 is attached to the computer and wait for the
“Connect” status, upon which choose to “Calibrate” the device.
Next select “Measure” and follow the instructions on the screen
for measuring both lines for the Fogra Media Wedge. If an error
occurs during the measurement process, online instructions will
indicate a re-measurement is needed. Upon completion of the
measurements an evaluation of the performance can be seen
in the “Results” section of Color Verifier. It will be clear whether
a PASS or FAIL result has been achieved.
Step 7 — Printing a Label to Show PASS Status
Upon hitting the tolerances and achieving a Pass result, the final
step in the verification process is to print the label and attach it
to the proof. The label simply documents the proofs compliance
to the ISO-12647-7 standard.
