Hi Carl,

I see you've been scratching away at this, too.   I've also been figuring
out how to use this.  I managed to figure out that the reference files
names are hard coded into Eye-One Match so that why we haven't been
able to get it to recognize other Ref files.  So I converted the 21 step
Ref file to an RGB description rather than Grayscale, and just overwrote
the existing i1 RGB 1.5 file (save it first).  This works like a charm.

Just use the ordinary step-21-random.tif file for printing -- in fact I
already had linearized print outs from before.   All you need to do is
run i1Match and scan the strip.  Voila instant soft-proofs and it'll
work for any kind of grayscale output scheme -- QTR, Roark, Piezo.
