QTR-Quadtone RIP

Hi - I am trying to create QTR profiles for Eboni 6 for Epson Hot Press Natural.  I am using an Epson 1400.

I am following the QTR user guide (Document Version 1.1 21 April 2005).

I am stuck on the second step where you need to determine the density levels of each of the shades of black.  My understanding is that I need to determine what each shade's density limit is relative to black.  To do  this, I look at the 100% shade of each ink and then determine where that  is on the black ink line.  The problem I am having is that each shades of black at 100% has the same density.  

I have uploaded scans of the ink calibration pages at:

These images were converted to RGB mode, but I am using Lab mode in PS.

Does something appear to be wrong with my calibration prints?

Thanks in advance for your help.

David
