Digital BW, The Print

I recently got an R-285 (so it�s called in Germany) I think it is
R-280 in U.S. I�m making black and white prints in my own darkroom for
years and wanted to try a simple bw-printing aproach (at least for the
moment) with black-only printing. I read with the MIS ink  this is
possible  because of the small dots of this new printers. After
installing the printer I was impressed by some first color-prints with
the claria inks on glossy paper. I tried claria-BO with some
experimentation with QTR and the first prints on glossy papers where
not too bad (I just modified the R-380 profiles in the advanced
adjustments-mode bit, but did not went into doing new ones) Did
anybody try this and are there profiles for claria-BO? I know there
are not to many fans of the claria inks here butwith a little
experimentation I think this is worth a try. What are your experiences?
