However, I agree too, that a number of designers and other suppliers
of digital files still prefer a shorter black. And even a number of
European printers prefer the shorter black.
They seem to work in an environment where a less stable process is
still needed.
I've been working as part of the with the Periodical Publishers
Association pass4press technical committee here in the UK to produce
best practice guidelines for digital file supply. We're now into our
second edition of pic4press , a document that defines the majority of
the UKs magazine markets agreed colour workflow. Both last year and
this year , we have recommended the use of the ECI profiles for colour
separation in the absence of any defined target or supplied profile.
However , I am not entirely at ease with these profiles , partly to do
with the issues above. This year we are producing our own profile for
glossy magazines that will be aligned with the PPA proof4press
accreditation process , and recommending the use of the ECI profiles
for other paper stocks ( once again when no other specific target or
profile is available).
The parameters for generating the PPA profile as agreed with the
publishers, repro houses , software vendors , printers etc ( all
represented on the main committee ) are :
TAC 310% ( max black 95% ) . Medium GCR .Black start at 35 %...so as
you can see , much in alignment with the above comments .
Personally , I prefer to build my own profiles using the FOGRA data and
ProfileMaker 5.. This gives more control and versatility over black
generation , and better rendering of our images both relatively and
perceptually.It also gives a little more liberty on TAC that can be
useful with some imagery. Our company now has a family of ISO based
profiles that we can use on an image by image basis depending on the
subject matter in question.

Yes, the ISO coated does seem 'better' then the Adobe FOGRA 27 profile.
Paul also kindly pointed out the link :-

Which proved to be assuring re using the FOGRA data and Gretag software
as an option.

But it shows in what dilemma we are and I have said that before:
We have and still need experts on one hand, but most of the people
working
in the (photo)graphic and printing industry aren't.
With my '(photo)grapher ' hat on , I'll take that on the chin , but
will point out that as a group , photographers are a lot more clued up
than is often assumed. It's more often than not the case that image
files from photographers are fine until the next person in line , be it
designer, or retoucher or pre press or printer , starts abusing them
