I'd re-fill your own.  I don't think MIS sells the LC in the Y cart.

You'll have best results with the diver and slider approach -- i.e., don't
use the RGB curves approach.  The reason for this is that the LK really
seems to help the image on un-coated Arches Hot Press.  So, you'll want the
driver to "think" a grayscale image with no color is being printed.  Sliders
should also be at default 0 position for this.  Today, with Roy Harrington's
Create ICC program, that may be the easiest way to linearize the system.  A
monotone curve in PS could also do it, if needed.

Good luck.
