QTR-Quadtone RIP

I just received the inks for the R1900 with my surpriser there are just two black inks and the glossy optimizer (Clear ink). I was under the impression that your need at least three channels for Black in order to have good result. Did I missed something? Should I order some more ink to print on Mate only paper?

Thanks,

Giuseppe
