Traditional color carbon and carbro were three color processes based
on continuous tone separation negatives and did not need a black.
Double transfer was generally used because registration was done by
eye and it is much easier to register a magenta image over a cyan
layer than a yellow relief over magenta. Double transfer also allowed
for the use of a wider range of final surface papers. In any event
the order of traditional carbon and color was such so that the yellow
image would always be the one on the bottom. This is because yellow
pigments are less transparent than magenta and cyan, and if left on
the top add an unpleasant kind of yellow glow to the image.
The Ultrastable color carbon system was based on half-tone negatives
and used black as the last color. It was of course based on
registration and done in the order of YMCK.
Since your system will be based on registration the correct method
would be single transfer in the order YMC, or YMCK if you decide a
black is necessary.
