Digital BW, The Print

I want to throw this question out to the group and hope those with loads more experience 
can answer.

Assuming thisi scenario:  you have your printer optimized using lets say the Piezo NK7 
inkset and have also set up Harrington's create icc for every paper that you have.  Step 
wedges are linear and the highligts dot free.  Your test print on an image that you are 
familiar looks great.  Your competitor across the street is running the same exact set up.

Now a customer walks in and tells you to print an image for them.  You run your NK7 
system for this print.  Your competitor is given the same file.  What is it that is going to 
separate you from your competitor?  (lets not get into price and customer service here, 
just printing skill) Is it how you translate the file and choose the best paper for it?  Or is it 
how you prep the file, maybe play around with the contrast and possibly fine tune the 
sharpening?  

As we move forward to turn key Digital Black and White solutions, almost everyone should 
be able to create good Black and White images.  I believe that several years ago, you could 
distinguish yourself from the pack just by running special inksets and special rips.  But 
that gap is quickly closing.

I'm starting to feel that good printing will be narrowed down to paper choice interpretation 
and file tweaking.  

Assuming the same exact set up.  How will a printing expert like Tyler Boley separate 
himself from the guy across the street?
