AFAIK it's a paper-only feature. Since ink doesn't cover that part of the spectrum (invisible ink aside:) ), ink should play no part in this...
Depends on the inks in my opinion. Fluorescence is not limited to UV absorption, with visible light it is possible too.
http://jist.imaging.org/resource/1/jimte6/v55/i2/p020201_s1?isAuthorized=noCyan dyes could still absorb light near 400 NM wavelength and emit above 500 NM. Depends on the UV-cut filter in an Eye 1 whether that fluorescence would also fit the context of this thread.
