QTR-Quadtone RIP

Frans,

Before delving into your question deeper: what inkset do you use 
(from the profiles you use I guess the OEM inks) and what OS are you 
using?

Good chance that indeed the problem is that you have not converted 
your file to the right icc profile. QTR works in the LAB space and 
assumes your image is converted to it. The GRAY-LAB profile come with 
the installation

C:\Program Files\QuadToneRip\icc\gray-lab.icc

Make sure you CONVERT the image to this profile and not just ASSIGN 
the profile to the image. QTR ignores assigned profiles.

The directory above also contains some other gray icc-profiles for 
matte and glossy papers. But I have never find them of any use.

Personally, I never touch the ink limit and gamma adjustment sliders. 
I regard them more as a last minute rescue feature than as a serious 
profiling instrument.

Good luck,

Joost
