QTR-Quadtone RIP

I am attempting to create some profiles for unlisted papers for the Epson 7500
K6 printer
with an Eye-1 spectrophotometer (Mac OS 10.4.10). All QTR related applications
are in a
folder in the Applications folder.

I have successfully created the text output files for the scans.

I am ready to paste the linearization info from the text output file into the
ink description
file.

I used the "K6-HahnePhotoRag" profile (the one I used to print the original 21
step chart).

The first message I got was: printer not defined.

I added the line: PRINTER=Quad7500 and change the GRAPH_CURVE=YES since the
printer
name was not defined.

I get the message: Could not find PPD file for Quad7500.

Where do I go from here?

Am I even using the correct files?

If not, how does one create an Ink Description File?
