QTR-Quadtone RIP

Apologies to the group. I tried to include the image on the replyHere's the link to the image: http://oi57.tinypic.com/5nuw5.jpg

In any case, this derails the main topic of the discussion which is the title on the subject line (Transferring curves from Mac to Windows)

    The RAW curves are empty. The first process was to load up, the second to linearise.I understand what you are saying - there should only one process, but this process is outlined on the QTR website (tutorial) and I also tested it (if it actually works)And it was indeed more linear on the second run. 
sample attached.

  ReD OgnitaI recently made a few curves using the RAW curves as a baseline. PC. - You choose the closest RAW curve to the type of paper. - Rename- Print a 21x4 Random

I am not sure if I am reading your post correctly. Are these two separate sets of instructions? 
If not, then there is a pretty important point you are missing. There is no two step linearization (at least not how you describe here).
I will copy your instructions here and insert comments below
- You choose the closest RAW curve to the type of paper. - Rename- Print a 21x4 Random target. - Read it using a spectro. - Drop it on the linearize thingy and a txt (out) file would be created. - Copy the values on the "linearise" line of the txt file- Open your the RAW curve that you have renamed via the Curve Creation- Input the Values- Click Show Curve (to save the adjustments)- Done.
Everything above is correct, and the resulting profile has now been linearized. What you wrote below is where it goes sideways.
-Print Print a 21x4 Random target again, using the Curve that you just did.^^The curve you just did is linear and printing it again is just for checking for linearity and creating an ICC profile for soft proofing^^- Read it using a spectro. - Drop it on the linearize thingy and a txt (out) file would be created.^^This part should be just checking for linearity^^- Copy the values on the "linearise" line of the txt file^^there is no need for this or anything that follows^^- Open your the RAW curve that you have renamed via the Curve Creation^^This profile/curve has already been linearized^^- Input the Values^^This Overwrites the linearization string with the linear measurement values from the second 21x4 target^^
- Click Show Curve (to save the adjustments)^^The linear values entered in the previous step tells the installation script that the raw curve is already linear and does not create a correction curve and you end up with the unlinearized profile^^
- Done.^^nope, just back where you started^^
I think what is not being understood is how the installation/ink partitioning program works through the ink descriptor file. This is a generalization, and admittedly, I don't know the specifics of the math or programming behind it, but here is roughly how it works.
It first takes the ink limits, cross over values and gray curve settings and creates a temporary set of curves. It then checks if there are toner inks used and if do creates temporary curves for those inks too. It then checks to see if there is anything in the linearize= line. If not, it creates the .quad file that contains the values from the temporary set of curves (this is an unlinearized profile). If there are values in the linearize= line, it takes those and creates an inverse correction curve to reach linearity, and applies it to the set of temporary curves and creates the final .quad file. At that point the profile has been "linearized". 
Any time you change a value in any of the settings and press "show curve" (or run the install script on a mac) it goes through the whole process all over again. Since it works "top down" and doesn't "know" if there are linearization values until it gets to that point in the ink descriptor file, it always creates an unlinearized temporary set of curves from the ink limit, cross over, and gray curve settings (There are some other things that it does to check for specific ink curves, which overrides the cross over settings, but that is a whole other "can of worms").
If I completely misunderstood your post and there is something in the QTRgui I am missing please point me to it.
