First, the easy question.  FS stands for Full Spectrum, a quad black 
inkset made by MIS that is similar to the piezoBW inkset.  As far as 
Custom Dot Gain, I'm only a small step ahead of you but here goes.  
In Photoshop 6, go to Edit/Color Spaces/Working Spaces/Gray.  Select 
Custom Dot Gain and you will see a typical curve with one point on 
it.  You can edit this curve for two different purposes.  
1. I used it to fine tune prints using the FS inks and the piezoBW 
software to try to match piezoBW prints done with piezoBW inks.  For 
this purpose you would have "Preserve Embedded Profiles" selected 
under Color Management Policies/Gray.  Changes to Custom Dot Gain 
will not show on your screen but will effect any grayscale prints.  
2. You can also use Custom Dot Gain to match your monitor to a B&W 
print.  In this case you would have Color Management Policies/Gray 
set to Off.  Changes to Custom Dot Gain will immediately show on your 
screen image but will not effect prints.
