Digital BW, The Print

Dear all,

I'm a long time user of QTR (on windows) and I'm still very happy with it. That is, for fine art printing. For more production-type of printing I regularly miss some options that other RIPs do provide so I'm looking around. 

I'm aware that some of you use StudioPrint, as I understand mostly with Cone inks since Jon Cone provides SP profiles with his inks. But does StudioPrint provide the same flexibility with custom BW ink sets as QTR does? 

I've installed the StudioPrint demo version, but do not see a way to get this done. One can define a multi-gray ink setup but I can't figure out if one also can e.g. add toner curves or use dual Eb-HP-PK just as QTR does.

Frankly, I would already be happy if I could just load data tables per curves. Then I could create curves in Excel and import them into StudioPrint. Is that possible? Is then StudioPrint sufficient or would I need ColorGPS as well (adding a significant amount to the bill)?
