Digital BW, The Print

From reports on the Imageprint yahoo group, it sounds like version 6 
of IP may give greater ability to tone and colorise black and white 
images but without losing the benefit of nil metamerism. There was 
talk of being able to run a colour profile and a grey one at the same 
time on a single print so that where R=G=B it used the grey profile 
but for everything else it used the colour - so you get the benefits 
of colour but pure neutral greys.

fine.  I can't really see much difference between feeding IP an RGB 
or grayscale file printed with the same gray paper profile.  You can 
certainly do everything you are doing today with respect to the RGB 
work and still print neutral b&w with IP.  (IP gets a little strange 
when you feed it a gray profile and try to print with a color paper 
profile, however.)

a great way to go.  With the realization that judging quality and 
desirability of what we turn out is largely subjective, many people 
that see the IP b&w side by side with the dedicated b&w systems find 
the results at least equal.  Some prefer the tonality that you can 
get with IP over the MIS or Cone inks.  And, some the other way.  In 
short, the IP b&w produces a good product.  The color is equally as 
good, although the difference between the IP color output and the 
Epson color output is not as great as the b&w.

the "pure carbon" inks that Paul Roark has been working with.  I've 
seen a couple of Paul's pure carbon prints, and for subject matter 
that would lend itself well to platinum, the pure carbon is really 
beautiful.  I can't match that look with IP.  I've been tempted to 
buy one of Paul's excess printers just to do the pure carbon printing 
on.  I probably won't, just because of room (I've already got a 9600 
and several HP printers) considerations.  But, the cost of dedicating 
a printer to that use is not great.
