Digital BW, The Print

Did some more testing and clearly, I was working with a bad cartridge. . . .  

Museo PR - Old K7 Cart 1.54
Museo PR - New K7 Cart 1.60

Innova STA - Old K7 Cart 1.54
Innova STA - New K7 Cart 1.60
Innova STA - Eboni Cart 1.66

HPR - New K7 Cart 1.63
HPR - Eboni 1.68

I tried Eboni as well. I knew it's DMAX was higher than K7, but now I'm wondering how a 
print would look with Eboni for K and Cone K7 inks for the rest?
