QTR-Quadtone RIP

Hi everybody,

being a new QTR user,
and hoping that QTR will be relevant in order to inprove my workflow,

I nevertheless got several problems in tentatively using it.

I'm working with mac osX leopard (macbook pro),
and I'm trying to use Lightroom 1.3.1 for printing results.

The printer is an epson r1800, with epson inks for color, black photo
and gloss optimizer, but a special black pigment ink for the black
matt ink, very near the piezography characteristics (have a look at
http://www.christophe-metairie-photographie.com for reference, "Noir
et blanc" tab) .

QTR has been installed without problems.

1)  QuadToneRIP2.5.2.dmg.gz, installation of the package + 
the r1800 profiles (version with UC epson inks).

2) QTR-Patch.dmg.gz for leopard.


--->I would like to use only the matt black cartridge in order to
print BO, but I understand that if I'm using UC epson r1800 QTR basic
profiles, every inks will be requested (color inks too...); am I right?
What would be the solution to request only black matt ink in my r1800?
Do I have to build a special profile with QTR utilities? 
with an inhibition of every inks but black matt ink?

--->When I try to use the basic QTR profiles for r1800 (UC epson
inks), under Lightroom, the only profiles that I am able to choose are
"QTR RGB Matte paper" and "QTR RGB photo paper". For instance, I can't
choose "GRAY MATT PAPER" and so on, which nevertheless well exists in
the same directory (/Library/ColorSync/Profiles/); they don't appear
among the possible choices of profil management menu in Lightroom.
Does anybody found the same problem? would it be a known issue? and a
known solution?

Thank you very much for your help.
Alain
