Why are the lite inks LC and LM the same density, and likewise why are the L and C inks the same density? Does it have to do with using this inkset with the sliders on the Epson Driver?

If so then wouldn't it be possible to use the warm ink in the LC position and the neutral in the LM position and likewise warm and neutral inks in the L and C positions and then mixing them as needed in QTR?

Any thoughts on this?

Thanks for your time.
