Digital BW, The Print

Tom,

The tweaked ink target prints bands of color if you use colored 
inks.  If you use quad inks, it will print those individual colors.  
The last band along the bottom prints a composite (based on the 
curves and ink limits for each ink) to show how they will look when 
combined.  I rarely use this target to build or modify profiles.  I 
use mostly the Target FOR Linearization and take readings with my 
spectro to find color shifts.  

I don't have profiles for most of your specific papers, but I do have 
a full series of 2200 UC profiles I built for Somerset Photo Enhanced 
Radiant White paper (cool, selenium, neutral, warm, sepia).   All 
these profiles avoid yellow inks completely, except sepia, which uses 
a fairly small amount.  

I almost always start with a good, similar profile and print it out 
on my new paper.  So, if you want to create a neutral profile for 
Somerset Velvet, start with a good EEM or Entrada UC neutral profile 
and print a target for linearization.  Eyeball it, or take some spot 
readings with your spectro to zero in on color casts, color 
crossovers, lack of separation, densities, etc.  If your shadows are 
a little weak and yellowish, you can add a little cyan and/or magenta 
to the shadows to neutralize them and add a little more punch.  If 
the highlights are too cyan, you can lower the ink limit of LC, use 
the toner slider to reduce it a little, and/or modify the LC curve.  
You could also add a little more LK since it is warm, especially if 
you need more density.  It's actually pretty easy and intuitive once 
you play a little.  

My warm profiles generally use only MK and LK inks.  My cool, 
selenium and neutral profiles use all but the yellow ink.  My sepia 
profiles use all 7 inks.  

Send me an email at home, lbdina@..., and I will email you a 
set of Somerset profiles.  They ought to get you very close to where 
you want to be.  If you don't like the toning, you can modify them to 
suit.  I built thise with UC inks for 2200 on a Windows XP platform.

Can't get the Tweaked Target to print.  Also, the 'manual' says the 
tragets should be printing in gray scale.  What I'm seeing is color.
