QTR-Quadtone RIP

Hi group:

I am developing my own curves and ICC profiles for QTR and Epson Velvet Fine Art for a 
Epson 2200 printer.  Everything looks great except my 95 and 100 wedges are identical.  Can 
anyone please tell me what is the best way to correct this problem.  When I printed the 
calibration page, I chose an ink limit of 65% black ...should this be lower.  I tried boosting the 
black and altering the shadow value neither of which made much difference.  

thanks

ron
