You're speaking offset press values, for setting files at the max and 
min dot a press can handle some presses require a 2 to 5% dot as you've 
sort of described... you set your whitest white in your image that is 
not a specular highlight with your white eyedropper (that has been set 
at the required dot percentage), letting the specular highlights (if 
there are any) fall to paper white. Setting your black point at a value 
of 13 gives the image a 95% black, not something you want to do when 
printing quads...
It's not the ink. It is the ability of the partitioned workflow/ 
driver/ RIP/ Profile/ whatever to separate the steps as you have 
prepared them within your file... I do this better than I write it, I 
hope that came out with some sense.
