Very clear, Ernst as usual. In fact, it's in the 95-100% range I was 
wondering relating it to Dmax. 

Again at a given dot size (forgetting VDS here), ink set... I'm 
assuming dot gain will be the ultimate factor in ink limtiation, 
meaning on one hand the paper on the other hand the dpi resolution. 

Say paper is given again, I'm left with dpi and a direct relation to 
larger dpi-smaller fixed dots (at 2880). I've seen you repeatedly 
mentionning smaller dots lead to higher relative dot gain (unless 
wrong) : so where do we stand in terms of reaching higher Dmax. We're 
better off with small drop or larger ones ? 

View like this I'd go for higher dpi and smaller dots. Basically, I'm 
still stuck with what best dpi reso to use despite hundreds of posts 
on the issue and Roy's mentionning 1440 is very fine vs 2880 makes me 
wonder, because the 95-100% will probably use larger dots and put 
together with your saying smaller increase dot gain and density make 
me thing Dmax can/should be increased with smaller dots.

I'm sure I've got something wrong here...
