representing increased percentages of CMY inks. The whole idea behind this
technique is for the user or the software to pick a point where the chroma
of the ink is maxed out, to "maximize" the size of a given printer/substrate
gamut, provided there is no ink dripping or puddling.
And because this is only a 2D projection of a 3D shape,
it's not actually a good way of judging the maximum
gamut properly, since the L* can still be reducing (hence
increasing the gamut), even if the C* has passed its maximum.
Possibly a better technique is to monitor the length of
the L*a*b* vector from white, and pick a point just before
the vector length stops increasing.
