Since I have no idea what kind of a carbon process you are talking about I
have the sneaky suspicion that there are two or three out there, possibly
four, who don't understand it either;-)

Is it a home-made process? A process described in a book? continuous tone? etc.

There is a market for any process that is easier and/or cheaper than what
is available out there, screenless, stochastic, or contone, IMHO. I don't
see why anyone would need a four-color process with continuous tone seps as
super dense blacks, i.e., raised about 0.5mm above the surface of the paper
can be obtained with just three colors.
