Hey list,
I was wondering...
There are a lot of endusers out there who are using the GretagMacbeth
EyeOne with UV-Cut filter to do profiling and/or linearization for
their digital proofing systems.
Others are using EyeOnes (or different devices) without UV filters.
Is there any official statement on the use of UV filters when
performing a 'proof certification' (measuring FOGRA MedienKeil)?
Thanks in advance,
Erik

Hello Erik,
Actually, the whole ISO 12647-2, The FOGRA characterization-data, the
profiles made from ECI, Adobe and other based on this
characterization-data and the quality-control for FOGRA-mediawedge is
based on measurement WITHOUT UV-cut.
So profiling of the proofer and an quality-control MUST be done also
WITHOUT UV-cut do get measurement-data and visual appereance consistent.
Actually, there is a discussion in the TC 130 (technical comittee, which
is developing ISO 12647-2) How to deal with optical brightners and how
to use Measurements with UV-cut. But this would result to:
- other Lab-values for paper, primaries and secondaries in ISO 12647-2
- new characterization-data
- new profiles (ECI, Adobe and other)
- new target values for the fogra-mediawedge
So there is a lot of work to do...

Jan-Peter,
Thanks for your info ont this, it is actually exactly what I hoped to
hear.
I've read the TC130 discussion, which actually triggered the question
again.
For those who want to read about this, here's a link to that specific
discussion:
(see: 8.1 ISO 13655 Graphic technology) http://www.npes.org/
standards/TC130WG3N541_Minutes-May05.pdf
While mentioning TC130, did they have some kind of official statement
on the differences between the characterization-data (27L-30L) and
the 'official' ISO color values?
Greetings,
Erik

Hello Erik, hello list
The FOGRA characterization-data 27L-30L are developed together with
several organizations like e.g. german federal associations of printers
(bvdm) or ECI. They are also supported already in several applications
like e.g. Adobe Creative Suite 2 and proofing solutions from e.g. EfI or
GMG.
Even, if they are the most used characterization-data for separation,
softproof and hardproof according ISO 12647-2, they are not official ISO
characterization-data.
The most official statement concerning the differnces between the ideal
ISO values and the realworld values of FOGRA 27L-30L can be found in the
update to the altonatestsuite package.
But this statement is from FOGRA / bvdm / ECI and not from TC 130.
If you are an owner of the altonatestsuite package, you will get this
update automaticly the next days.
