First of all, thanks for your answer on- or offlists.
As some of you asked me, I precise that I work under Debian AMD 64
I work with the packaged version for Ubuntu of scribus-ng (64bits arch),
and ICC-Profiles coming from Debian AMD64 repository (I should verify
that, I'm not so sure).

Well I found that on the web. That's why I did use LStar-RGB.

Do you mean when the printer service don't know much/anything about
colour management ?

That's what I'm about to do.

In fact, I don't have send the proof yet, cause it's thet contract proof
I'm trying to get.
In fact, I don't want to work with the printer agency which I named in
my first mail, cause they're quite bad, etc., but as they're just next
to my house, I just want them to print the proof. And they can't do
twice the same.
