The best way is to get the appropriate CIE standard values for the
density filter functions (I am not in the office so I do not have the
standard at hand) then do the spectral calculations in a spreadsheet.
Or, you can take an easier route. SpectraShop 2 (http://rmimaging.com/
products/spectrashop/spectrashop_index.html) can take i1 readings
directly and it displays Status A, E, M, T, V, ISO 1 and ISO 2
density values.

Greeting to All.
I am not sure this is the right place to ask my
question but I am at least hoping that someone can
point me in the right direction.
How can I convert readings taken with my iOne
Spectrophotometer into approximate density values? I
know that
this would not be absolutely accurate and could not
be
used for direct comparison to a densitometer. I am
looking for the ability to use them as a reference to
themselves on proof sheets that we are making for
color correction purposes.
Consistancy from sheet to sheet, day to day etc.
At one time I had a formula that I had gotten from
Gretag MacBeth but can't find it.
What say ye?
Thanks for any help here
Oakley
