Digital BW, The Print

Julian,

Before you run out of the Piezo inks you might want to print some 21-
step wedges using the profiles and papers you are most likely to be 
using. When you convert to the FS inks print these wedges again and 
compare. If you don't have a good match to the Piezo inks, try 
adjusting the dot density and gamma in the Piezo drive to see if you 
can get a match.

Another approach would be to work out a universal curve that you 
could apply to your images before you go to the Piezo driver to get a 
match.

Alternately you could and probably should do a new Custom Grayscale 
curve in the Color Settings of Photoshop using a wedge printed with 
FS inks. That alone might do the trick. Save the Piezo curve in case 
you decide to switch back.

I think if you do some calibration work up front you should be able 
to operate as normal once you have adjusted for the differences.
