Yes, but they are not the same density as the LK and LLK.  Most of the MIS
inksets have used a dark carbon that uses the old FS-C density.  The light
carbon is the usual 30% dark to 70% base dilution.  So, both are a bit
denser than the LK and LLk.

> Can THEY be used in the K4+cm approach?

You could use them in that type of approach.  However, to be consistent with
the k3 inksets, I prefer using the k3 densities.  The idea is to get on a
learning curve and make curves, etc. that are easily adaptable to the k3
printers and standard inksets.
