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....
