   where the values are the density of the light ink compared to the
   ordinary one. What happens if you specify a "light ink density" and
   then don't supply a buffer to dither_cmyk(), I don't know!

You'll get a bus error or a seg fault when the dither code tries to
write to the nonexistent light buffer.  That's why the out of
specifying a zero light ink density; that turns off light ink printing
for that color.

   Robert, does this make sense or am I writing drivel? How do you work
   out the values of the dither knobs? Do you print colour gradients and
   look at the transitions?

It makes more sense than anything I've written about it (because I
haven't gotten off my duff and documented this yet).  As far working
out the transitions -- that's precisely what I do.
