Digital BW, The Print

I am still worried that my new Ultratone inks may be wrongly 
labelled due to the issues I am having with the curves.  I have 
triple checked my installation - it is OK and the ink order is :
K - black
C - Dark grey
M - Dark blue toner
Y - light grey
PC - Mid grey
PM - light blue toner.

IS this correct?  I couldn't find info on the positions anywhere, a 
short reply would be a great help.

Thanks 

Steve
