Richard,

This is a rich answer I had to read several times, not only because english isn't my native language.
Thanks a lot.

I don't use any partitioned profile and I'm not familiar with cross over settings, though I understand how it is important for printing positives.
My use of the 1400 printer for making negatives is quite basic: each channel is fed with the same gray ink dilution - Cone's InkThrift CL black at 30% - and each curve goes from 0 to 100.
I set the ink limit to adjust the density required by my process, and adjust the curves - all the same, but could be different - to get the tones where I want them to be.
So I only have lots of 30% gray droplets making my negatives.
I currently set the default ink limit at 10, lower than 20... But this means 6X10=60.
Then if I made a 25% dilution, I could use a higher ink limit - as long as there is no puddling or other complication... - and get the same density.
In my view, this means more (more transparent) droplets and I like the idea.
Would you say both ways would make similar negatives, with the same information, or the same quality of information - if that makes sense?
The opposite way would be to use a very opaque ink and decrease the ink limit, which would lead to a very different kind of negative, the extreme being a halftone film.
That's not my approach.

Then I have related question.
Does the ink limit have an effect on the droplet size?
With variable size droplet printers, what will determine when a bigger droplet will be used?
Do we have a way to control that?

Thanks again,

Stefan Christiansen
