There are UV-cut Spectrometers on my Z3100/Z3200. Next to them I have an
UV-enabled Eye One that replaced the UV-enabled SpectroCam, the last is
still here but too old now.
Where I expect more UV/FBA effects I use the Eye One, for example on
varnished canvas targets. For the SpectrumViz paper white spectral plots
I needed an UV enabled spectrometer anyway.
In general I think if you want to avoid UV/FBA effects in your prints
and profiling then take media that do not have FBAs or just in small
quantities. Safer in any environment. Measuring with an UV-enabled
spectrometer should then make no difference or slightly better compared
to an UV-cut model. If FBA papers are measured with an UV-enabled
spectrometer and not displayed to UV+light in practice then measuring
the FBA effect and compensating the effect in software to a UV-cut
measurement on the spectral data seems more sound than the other way
around. Argyll does the first. There is of course some contradiction to
start with FBA media and not using the FBA effect in the end. But given
the fact that of the >70 RC photo papers I measured only 2 show no FBA
content there are practical problems to get the right solution. It will
not be better with offset papers.
