I got it Thanks Martin (thanks John).

More questions:

But why is one required? Does Cone make profiles that make prints that match
ICC standards, so that if your monitor is properly profiled, you'll get a
good screen to print match.

Is it that they do, but IF you still don't get an exact match, because your
monitor isn't perfectly profiled, or because each printer and paper batch is
marginally different from another, you can custom tweak it to perfection?

See the distinction? Are you being asked to compensate your monitor because
the profiles miss their mark, or are they providing you with a workaround
for an improperly calibrated/profiled monitor? Do people who have well
calibrated/profiled monitors NOT need custom dot gain curves with Piezo?

Furthermore, are Cone's profiles ICC profiles that are stored in the
Colorsync folder (on a Mac and whatever the equivalent is on a PC)? If so,
why not softproof the image through the profile? I never hear that spoken of
on these lists.

What happens if you are working a grayscale file with a custom dot gain
curve and then convert to RGB--is the dot gain curve somehow carried over
into the RGB screen view?

And what about dot density? I never hear that spoken of on the Piezo list.
From page 29 of the instructions:

"Dot density is used to control the amount of ink put on the media".

Regarding the recent discussion of getting better blacks on Eclipse Satine,
would increasing the dot density be of help there?
