Digital BW, The Print

Hi Folks,

Since the 1400 has the fine 1.5 peco heads, I would like to try BO with the Claria inks. My understanding is that selecting grayscale on this printer actually uses more than the black ink channel.   If I purchased Roy Harrington's QTR, would this allow me to print true BO with the Claria inks? Would this be suggested?

I like the fact that Claria prints are durable and water resistant- since the BO does not spray droplets on areas of the print that are pure white, I am concerned that the print would not be as protected as a full coverage print.  Does anyone have experience with this?

Thanks for any input.
