Digital BW, The Print

I have not taken an extensive look but my GM i1 profiles allow checking ink
black without checking paper white but not the other way around.  The point
Walt was making is that he would like to check paper white without checking
ink black.  Such combination is not possible with the GM profiles and I am
not sure it makes sense anyway.  The GM profiles don't have bkpt tags.  None
of the Epson 4800 profiles I looked at allow you to check ink black at all.
None have a bkpt tag.  When I was asking Phil Green about this tag he said
words to the effect that it was "not a mandatory tag in the spec, you can
put it in but you need an application that can make use of it."  We're just
a bunch of colour blind guys who don't know squat about colour, wandering
around in the dark and grey.  Perhaps this is illustrative of the ground we
need to cover, who knows...
