In general the best strategy is to make the press behave as much as
possible in line with ISO aim values. If your dot gain is too high ,
bring it down to the ISO aim values by using plate curves (should be
easily done with most RIPs out there).

We made testprints with pressprofile targets with
linear plates and
the DG was about 18%@40. Then we make the pressprofile and in the
processed PDFs the DG is 14% and with right colors. We will not get
that close to Fogra39 if we only use curves in the CTP. Greybalance
etc is tack on. (The press-profile compensates for the
characteristics of our presses/ink/etc.) You cant achive that with
curves?
Maybe your ink/press/etc is more "ISO-like" then ours?
