Digital BW, The Print

How would you proceed to produce a print with pure BW parts and  some colored ones on a 9800 loaded with K3.

QTR alone can not do it, Imageprint seems to handle this but is very expensive. I've not look at Qimage, but to my understanding it's not designed for this.

Any suggestion except a first class color profile (uncontrolable colors will still be there) or the expensive Imageprint ?

Thanks.
