Digital BW, The Print

Hi,
I finally got my R1800 with Eboni 6 ink setup. Though the ink is from someone who had an excess of ink bought from MIS last year. Which I have now acquired. I did a QTR print calibration of all the inks.
Now what has suprised me is that some of the ink is not all black? Well NOT different shades of black?
My 
MK (EBK) is infact black!
Cyan (Eb6C) is a dark cyan
Magenta (Eb6LC) is a light cyan
Yellow (EB6Y) is a dark brown
Red or Light Cyan (Eb6LM) is a greyish very light brown
Blue or Light Magenta (Eb6M) is a black

I'm just wondering if I got some dud inks?

The QTR curving looks like a can of worms! I do have a Colovision Printfixpro spectrometer, and each inks do not seem to be sequential from ink to ink?
Perhaps I need to figure out a limit on each ink to make them sequential? 
Has anyone had any success in utilizing all 6 inks in one print?
Thanks
