First option would be to try profiles for similar papers. I don't know what is available for 3880, but something like silver rag or some other Baryta coated paper would be a good start. These usually get you close. I would definitely start there and see if you are happy with your results.
You could then modify one of those to create your own profile for your papers. You have the color munki and modifying curves isn't too hard once you get the hang of it. There are several tutorials out there about this. I would recommend Lou Dina's or Amadou Diallo's. I think they are both in the files section here.
Another option would be finding a profile that is close and create an ICC using the create ICC feature of QTR.
You can create these for each set up you use right down to the toning options you select. If you go this route, I would suggest using QTR Print Tool to avoid the color management issues with Adobe/Apple/Epson. I really like Print Tool anyway.
I have used ABW and QTR and prefer QTR for several reasons. 1) ability to split tone gives much greater control. 2) It uses less of the various color inks in the mix, which hopefully will lead to less long tern color shift. I checked this by scanning a sample and zooming to the dot level. There is clearly less color dots.
Sepia tone uses no color (check the profile...they are shut off)
