QTR-Quadtone RIP

I'm having a problem with Iford Smooth Pearl printing.  I have a b/w image and it's profile 
is QTR - Gray lab.  When I print on my EP 4000 using the  QT RIP on Enhanced Matte paper 
using 

mode: QuadTone RIP
curve 1: UC-EENHMATTE-cool
curve 2: UC-EENHMATTE-warm
Black ink: matte
Tone Blend: 90-10
res: 1440
High Speed: faster
ink limit: 0
Gamma: +3

the results are wonderful!!!!

with the Ilford Smooth Pearl:

same mode
curve 1: UC-ISmoothPearl-neutral
curve 2: UC-ISmoothPearl-carbon
ink: Photo Ink
tone blend: 90-10
rez: 1440
HS: faster
ink limit: 0
gamma: +3

these prints are mottled with blue and pink (magenta) swirls over all

ANY THOUGHTS FROM THE EXPERTS??

Sounds like one of the profiles has been corrupted some how.
You could try each of them by itself -- ie. blend 100-0 and 0-100
to find out which one is bad.

Which version of QTR are you running?

I'm running 2.3 on OS10.4 and PS CS2

Same result using the Ep photopaper profile and using Ilford Sepia settings

And same results using PS CS

I don't see any obvious problem with the profiles but I currently don't have
a 4000 available to try it.  I'm not sure exactly what you mean by
photopaper profile and ilford settings.  You should try one profile at a time to
see if there is one specific one in error.   The Epson Premium profiles would
also be a possibility for the ilford paper (they are for 2880 though).

How does one tell what printer resolution a QTR curve is designed to be used
at, or are they all normally designed for 2880?

The name of the curve has "2880" in it.
