I'm not sure what you mean here.  QTR does convert an RGB file to gray scale, as I understand it.  On the other hand, whatever is in the cartridges will be printed, so if there is color there it will be printed.  QTR, however, is a B&W rip, not intended for color work.

See http://www.paulroark.com/BW-Info/BW-Dye.pdf  

Note that the dyes and base I'm talking about there are Claria type dyes.  I have no idea whether the base formula there is appropriate for the dyes you're dealing with.
