Peter Mosley posted a .pdf file that is in the Files section of the carbon forum with similar spectrophotometer measurements, "QTR Transmission Data" is the title as I recall.

K is definitely the most linear of the OEM inks, but yellow is not far behind in the wavelengths that are useful in alternative printing.

I have worked with many different light sources and negative substrates but never found a case where the cyan was in fact a good UV blocker for alternative printing, though the fact that it blocks very well by densitometer reading clearly suggests that possibility.
