I have been using my own terminology for these two approaches and if I should instead be using preexisting terms, I hope someone will correct me.
For the traditional QTR, multiple gray dilution approach where each successively greater dilution of black ink is set to replace the previous dilution at the same gray density as the darkest of the new dilution, I refer to this as using the inks "in series".
When inks are set up to just copy the curve of MK, I call this "in parallel".
So, let me have it. Where have I gone wrong? (Wait, I have an ex-wife for that.) Just tell me if there are already existing terms and what they are?
