Thanks, Paul... here's a related question: what exactly do we mean by "Black Only" printing. Is this related to that option in certain earlier Epson drivers? Or does the term have a broader meaning, that we are using a set of carts containing one or more undiluted carbon pigment carts but also some various dilutions of the carbon pigment - thus necessitating QTR? 

I will have to study the remaining portion of your answer...
