I assume you're using QTR.  People use various methods to match the 
print to the monitor.  In QTR there are ICCs that can be used in soft 
proofing or to convert to.  I prefer to edit in Gray Gamma 2.2, so I 
print using a conversion curve first.  The one I use is at

You may, however, have other problems.

I have not made profiles for glossy papers, since the 3MK setup is 
for matte paper only and Eboni.  You may need to not only find the 
best setting for dmax but also re-work the basic curves that were 
made for the matte papers and 3 Eboni carts.  The approach that is 
outlined in the Notes of the Dmax and Start profiles in the 1800-3MK 
QTR folder should be helpful in finding the best ink limit for the 
best dmax.  Those curves may also be good starting points, but you'll 
need to look very closely at whether they are posterizing in the deep 
shadows.  You can manually re-work those curves.
