I have set up an epson 1400 with eboni 6 inks.

The 1400 ink order is Y, K, LC, LM, M, C.  I have printed out the ink separation chart for 6 inks.  However, it is ordered as Black, Cyan, Magenta, Yellow, Light Cyan and Light Magenta as inks 1 to 6 respectively on the separation chart.

I have calibrated my 3800 for 3K printing on various papers previously and am used to the separation chart printing inks in the same order - ie black is first and is used to assess ink limit with LK and LLK then assessed for ink crossover.

How do I proceed with the eboni 6 set up?  Do I measure the INk 1 = Black on the separation chart to determine the ink limit, even though the eboni MK ink is in the second slot?  Then how do I proceed in terms of measuring the ink crossovers?

No doubt a simple answer but grateful for guidance.
