Digital BW, The Print

Sören,

I guess I was a little cryptic.  In the QuadToneRIP dsitribution there's a
folder CurveDesign/Eye-One that contains target tif files and reference
files.  step-21-random.tif is a 21 patch target, the new Ref file is
just the text I had in the previous post -- just copy and paste into an
plain text file.

I guess this warrants a comprehensive writeup of the technique.
