Hi..
I'm really sorry, but there is a mistake in my mail...
I was looking at values with black backing from ISO 12647-2 and Isocoated
characterisation data is measured with white backing . But this agrees with
I said about the differences between ISO and ISOcoated, because
unfortunately there are using white backing coordinates, and ISO says very
clear that there are ONLY informative..
Sorry again...

Subject: ISO12647 Vs. ISOCoated and more...
Hi to all...
I would like to share our experience, and why not, our disappointment,
about the ISO 12647, the ISOCoated and everything involves.
Only one month ago, we passed auditory and they certified us at ISO
12647-2. This means a bigger effort than what we had expected, but we got
it. Paralelly I was lucky to take part in a course the ISO 12647 taught by
Erwin Widner, president of UGRA.
The issue is: I do not understand how it is possible that the ISOCoated
does not fill the rule ISO 12647-2 and we have the evidence:
YELLOW: ISOCoated L 89.68 a 4.45 b 94.69
ISO 12647-2 L 88 a 6 b 90
Taking into account that the maximum tolerance is 5, it is obvious that is
out of the rule. Besides, the Blue goes nearly to from 10 although it is
true that the ISO does not require anything at this respect.
But there is more....The other primaries get also close to the limit. For
example, our form was quite nearer the normative than the ISOCoated.
The biggest problem is that there is a feeling in the promotion sector of
ISOCoated as a solution to the differences among printing companies, when
the reality is that a sheet which fulfills the rule ISO 12647-2, a little
or nothing resembles the Altona Suite or proof in ISOCoated.
We have to add to all this the excesive permisibility of the normative
tolerances. I have got sheets which fulfill the normative ISO in different
weight of paper taking advantage of the limits of the rule which hardly
have a similarity among them so....imagine the resemblance between them.
Not to mention the little bugs that exist in ISO as in ISOCoated ( the Lab
of traping, grey, etc)
This worries and puzzle us as printers, as a photomecanicians, as a
designer and as a photographer.
To summarize, What advantage do I take to fulfill the rule ISO 12647-2 if
the extended and promoted profile ICC does not fulfill it? Is it logical
that we have to equalize in our press the ISOCoated instead of the norm
ISO? And finally, What is a press the ISOCoated for realized in some
supports of low quality when the demanded works in colour are usually
printed in high weight papers (170.-200grs) and 170-200 lpi or even
Staccato, where the colourful answers has nothing to do with it?
Thanks in advance....
