Be sure to read http://www.paulroark.com/BW-Info/UT14.pdf

Note that the K position is matte black, not glossy photo black.

The C and M inks are types of PK.  They are what you are going to use to
generate the black, not the MK that is in the K position.

I'm guessing that is what is going on.

The LC and LM are Lk-density inks.

To the extent it is consistent with the tones you want to achieve, use C,
M, LC and LM.  You can make a cool and a warm profile and mix them with the
sliders.

I hope this helps.
