Digital BW, The Print

Hi Everyone,
I am using the NK7 inks and have one printer set up on a G4 which  
acts as a print server with neutral and wish to have a second printer  
set up on the same computer which would have the sepia NK7.  I  
installed a epson driver for machine 2 and  from re-reading the  
literature it appears that I need to install QTR for the second  
machine .

1.  I tried to drag and drop another set of curves in the drop box  
which at the moment seems to be on the desktop.  G4/o.s.x. 10.4.8/  
R1800/N.K. inks

2.    I tried following the directions for installing profiles from  
other sources by creating another folder on the desktop, dragging the  
profiles into it and running the install script for the particular  
printer.

3.In the Curve Design folder there is a folder called Printers  ( an  
alias)  where the original lives I cannot figure out)   None the less  
I tried duplicating the Quad 1800-K7.ppd and then re-naming it  Quad  
1800-K7-2.ppd but that didn't work either. I am now out of ideas and  
am hoping someone can help me as between clogged print heads and this  
I seem to be at a complete standstill Printing wise and have been for  
the past 3 days.

Does anyone know where this stuff resides.  I tried spotlighting it  
and the only thing that comes up is the stuff on the desktop which  
seems to be an alias.
Thank you anyone and everyone who has an answer.  Siobhan
