Digital BW, The Print

Dear all,

Finally found the time to start my half-broken R1800 as BO printer.
Using: Farbenwerk cleaning cartridges - QTR - PK and MK inks available.

Made some decent prints after first install with Farbenwerk MK in R+B position - BO-2K printing.

Now I am wondering, what to do with the other 2 free positions (left side of head (positions 1-4)is not working anymore), PK and GLOP.

I can make any combination of inks in the 4 cartridges, or do them all with MIS Eboni Black or anything.

What can you experienced users advise?

Thanks for all reactions, will also post in QTR Yahoo group.
