You seem to be viewing this backwards; your print 100% Cyan, and read the
result as a Lab value. That tells you want value will result from that
recipe, and also what values of Cyan will be out of gamut on that device.
Then you derive an inverse table from all those values for the other side of
the profile. (Gross oversimplification).
