Digital BW, The Print

Well I'm a little confused about how many shades of carts there are in the EB6 set. I see references to both six and eight colors. Of course, the 4000 is an eight-color printer. 

The Eboni set of 4 oz bottles and empty carts would be an inexpensive experiment. I already have QTR.

On the other hand, Cone inks seem expensive and less flexible in that it looks like you have to pick your b&w tone and surface before the fact.

On the other other hand, I just did my first 4900 Epson driver b&w print on Moab Colorado Satine and see no color cast with my old eyes.
