QTR-Quadtone RIP

Hi Paul,

Thanks again for your reply. I was under the impression that QTR has the tools to make an ACV curve and an ICC profile, using the density data from the 21 step printout and the data from the linearised curve.
In the folder "Program Files > QuadtoneRIP > Eye-One" or the mac equivalent, there are 3 program files QTR-Create-ICC, QTR-Create-ICC-RGB, and QTR-Linearise-Data. I have yet to work out how to use these tools. The first step is to use the ACV curve. How is that created?

I was planning to do this to be able to "Soft Proof" the images before printing.

With your suggestions and advice I was able to create a good profile using the UTFS-N 4 colour 6 ink set in my 1410 printer. The results look good and I am pleased with the prints. I should have given you some feedback earlier but I have been out of the state for a few weeks. 

Cheers
Greg Nixon

My experience in attempting to explain the process and helping others suggests that unless you are very experienced with acv curves, it's too frustrating to try.  I generally recommend people stay with the curves I've made and include in my Zip files that contain profiles for the various printer/inksets I've used.

Second, try some of the ICCs that have been provided and see how they work.  If the profiles are less than perfect, the third thing to try is to simply re-linearize an existing profile -- QTR rip or Create ICC-RGB.
