QTR-Quadtone RIP

Hi Everyone,

I've been using QTR for digital negatives for a while, on 2200. R1800, and 9800. I have 
Version 2.4.x on a G4 with OS 10.4 and 2.6.2 on a G5 with 10.5. I write my own profiles 
which are a very simple syntax: a separate curve for each ink, generated from a 
spreadsheet.

I include a sample file below, with the curves simplified for the sake of space.

Recently I offered to write a profile for a friend who has a 3800. (I don't have one here). He 
can't get the profile to load correctly; symptoms no graph generated on loading and 
doesn't print.

He is running 10.3.9 on a G4 and 10.5 on an Imac, Intel, I think.

I can e-mail the profile to myself and, with the appropriate change to the printer name, 
load it on my 9800 and print. I can e-mail him a similar profile for his 2200 and that 
works fine. He can download other people's profiles and they work.

What am I missing about the 3800?

Thanks for any help!

Ben
