No, the actual ink density of the droplet, but I can't think of a way 
to express it so that it would make sense at the moment....

IF the nozzles are firing in a linear fashion using what I can't 
figure out how to express from above this can be accomplished in the 
same row of nozzles in one pass. Maybe "mixing" would be a good 
analogy? You could effectively vary the tone of a fixed tone ink  
(within its tonal range) by varying the density of the ink droplet 
and overlaying these different densities in one pass to extend that 
tone before the next tone would come into play. As I have said Nij, I 
may be a mile off. Maybe it is truly just magic <g>
