For K only, just convert CIE-Lab to CIE-XYZ and use Y' for the

There are many examples of XYZ to density calculations on the net.
If you can't find them, just let me know!
I actually put together a spreadsheet for XYZ-to-density per Bruce
Lindbloom's formula (formulae?) but I'm venturing into new territory
in terms of press calibration and I've settled on L*/density
relationships as one of the metrics I want to use. Or maybe I'm just
to lazy to redo all my new worksheets and change them over to XYZ!
