Yes, I'm using Press Ready.  I just got it and am getting used to it, 
but already I can print neutral greys and I'm happy about that.  I 
found that I had to increase the RAM allocation to both the Press 
Ready RIP and the Press Ready DTP to prevent repeated crashes.

So, let's say that I printed on a paper sample and it gave me 
bleeding at 100% but looked fine at 90%.  Most of the callibration 
chart squares printed with sharp edges, but a number (say 10%) of 
them are bleeding over into the adjacent squares.  Any suggestions on 
a starting point for the controls on Profiler CMYK?

Dot gain?
Black ink?
Total ink?
Black generation?
UCR amount?

by the way, a test prints of artwork I made using the first 
approximation CMYK profiles is looking quite nice as far as color 
rendition.  I feel like I'm on my way to making some very nice prints.

Thanks, David.
