Digital BW, The Print

I only played with the scanning import just to try it out, since I 
use an Eye One for linearization.  You should probably check with 
Bowhaus to be certain, but this is what I would probably do:

1.  Scan the printed target RAW ~ no corrections, no conversion, no 
black or white point clipping, etc.  I would want to see exactly what 
the scanner sees without any compensation.  For linearization, all 
you really want is brightness levels anyway.  I guess you could scan 
in grayscale mode if your scanner supports it.

2.  Bring it into Photoshop RAW.  Again, I wouldn't assign or convert 
or alter the data in any way.  You want to retain the luminance 
levels as read.  I'd just straighten it out so it is horizontal, 
clean up an blemishes or specks with the clone tool, if required, 
being sure not to change the tonal value of the patches.

3.  Save as a TIF file.

4.  Open IJC and import from scanner on the linearization tab.  Swipe 
the mouse over the data from left to right and the data should fill 
in automatically.  

I'm not sure if this is exactly what Bowhaus would recommend, but it 
makes sense to me.  You would not want to alter the tonal value in 
any way, otherwise I would expect your white point, black point and 
linearization to be inaccurate.
