Re: [QuadtoneRIP] How to produce an effective/accurate dot gain curve

2012-11-05 by Paul Roark

One write-up of how I use or recommend people start with QTR starts at page
11 of http://www.paulroark.com/BW-Info/Eboni-4-Plus.pdf .  I think the
approach would apply to most inksets.

I rarely use the tabs to control the inks aside from the linearization tab.
 Usually, the default QTR partitioning curve plus linearization is all that
is needed.

Determining the individual ink limits and densities are the key inputs that
you'll need to determine.  Even there, QTR seems relatively tolerant of
variation.

I do tend to use a black ink limit that is slightly less than where the
dmax was -- using the Black Boost for the end of the black curve.  But this
is not necessary either.

I'd recommend you start simple.
