QTR-Quadtone RIP

I'm new to the QTR experience and dispite reading and re-reading the 
user guide I am not sure how create my first new curve.  I've printed 
and examined the calibration ink pattern page, but I'm not sure which 
100% black, I should be comparing to which other black/gray ink.  The 
example has two black inks, the R2400 has three.

I've also tried to search through the posts on this group but have not 
found specific information about how to do this.  Does anyone know of 
any furtrher documentation or user written instruction about how to 
profile the R2400 using this inkset?  Any assistance would be greatly 
appreciated.
