QTR-Quadtone RIP

i'm attempting to create a digital negative using an epson 3800 on
pictorico ohp transparency film. in the bob k. folder i've put a jpg of
the scan and the qidf file i'm using.  if someone has time could they
take a look at steer me in the right direction?

thanks,
bob k.

Looks like the partitioning is at fault. As an example, the Silver Rag 
warm profile that's part of the qtr download looks like this:

N_OF_GRAY_PARTS=3
GRAY_INK_1=K
GRAY_VAL_1=100
GRAY_INK_2=LK
GRAY_VAL_2=52
GRAY_INK_3=LLK
GRAY_VAL_3=15

Yours looks like this:

N_OF_GRAY_PARTS=3
GRAY_INK_1=LK
GRAY_VAL_1=30
GRAY_INK_2=LLK
GRAY_VAL_2=11
GRAY_INK_3=K
GRAY_VAL_3=1

You've also got some copy_curve stuff going on and I'm not sure what 
you're trying to achieve there. I would try using one of the existing 
profiles as a starting point.

i've been trying to use ron reeder's 'using the quadtone rip to print
digital negatives' manual as a guide.  i'll double-check the numbers,
and compare it to an existing profile.

thanks,
