Graeme,
This is my thought exactly!
This is additive color that starts from Black and illuminates additively.
However this is only the part my mind is wrapped around, the previous note
about the graduate project is still the case.
The complete project is an overlapping or maybe even some other term!
There is both a subtractive color profile for the standard light color
space and the additive profile for the blacklight color space.
But that is so far over my head that it hurts.

Maybe. It depends if there's a useful printing process there or not.
It doesn't actually matter what the physics of the process is, there
just needs to be one where (for a notionally CMY or CMYK process),
zero toner = a light/whiteish color, and maximum toner = a dark/blackish
color,
and there is some logical control over the hue of the color being
reproduced.
People have used print profiling on fired ceramic glazes with modest
success,
and they often have fairly bizarre responses compared to a press.
But it's unclear what sort of printing process David Lewis has.
Conceptually it could be more like an RGB additive process, if
(say) the illuminant is actually UV and if three colorants emit Redish,
Greenish and Bluish light under UV, and the substrate is black. But if
that is the case, then it would need to be profiled as an RGB device.
Cheers,
Graeme.
