Digital BW, The Print

Good question.  I have two thoughts about it:

1) In a RIP print a Cyan/Magenta dot is a fully exposed batch of that
ink.  In a mixed carbon ink the microscopic pigment particles are
surrounded by carbon particles, so maybe the pigment particles are
offered some protection by the surrounding carbon on that microscopic
level...

2) Because of the mixing on the microscopic level, I wonder if the
desired print toning can be achieved using less pigment?  This seemed
to be what Bob was implying.

Clayton
