needs a 4000?


Roy & Carl,

Can you tell whether adding any Eboni to the dark grey increases
or
decreases the density?

I get a denser 100% with both of the UT2 dark grays than either
one on full.
Since the Epson driver doesn't tell me what it's doing, I'm not
sure if the
total ink limit is increased, some Eboni is being added, or some
characteristic of having the 2 inks is better than one.

Paul,

Could be the result of more bleeding and/or a better use of the
total of nozzles (more spots are covered by smaller droplets with
both inks at 50%). The last is better if it isn't also resulting
in more bleed = shadow detail loss.

The total ink limit in itself isn't the only factor, smaller
droplets that deliver the same quantity of ink as the total of
bigger droplets have more ink/paper boundary length and that will
usually increase bleeding/dotgain. The same happens with finer
screens in offset.
