QTR-Quadtone RIP

Tom:

Thanks for all your suggestions..I'm on a mac so I don't use the  
QTRgui version..
I have great seperation of the blacks in my linearized curve, it is  
only when
I then use that curve to print the wedges again and create my icc  
profile t
the problem is when i now use my curve and icc profile together that the
blacks are blocking up, I've tried lowering my ink limit from 65% to  
55% when I print
the ink seperation page and then relineazing etc, but the problem  
still persist when I
create and use the new icc profile...I'm still not sure why this is  
happening
