Digital BW, The Print

Hi,

With the latest Quadtone I'm printing with Piezotone, Photorag and the 1160-fs file. 
Most tones are right-on when compared to the monitor - the dither is excellent by 
the way. But anything above 5% K burns out - only paper white is visible. Instead of 
doing a completely new profile I was wondering if I can modify information in the 
original 1160-fs file to hold the highlights? If someone could point me in the right 
direction I would really appreciate it.

Here's the file info:
