Let me add to what I was thinking. I realize that the UV information is
missing from measurements taken with a UV-cut device. You wouldn't be able
to simply say a measured value of X should equal Y. What if you could,
though, plug in a variable representing the OBA in the paper?
This value could be a range, say 0 to 10. Paper with no OBAs would be 0
while paper with the maximum amount of OBAs would be a 10. As long as you
knew what the value was for a particular paper you should be able to derive
a fairly accurate simulation of a non-filtered measurement. You would also
have to know, and the equation would have to account for, the level of UV
light in the light source representing the simulated measurement. Of course
you would have to have a standardized way of specifying the OBA value for
any given paper. Assuming such an OBA rating standard existed, would this be
feasible?
To my original question of does such an equation exist, I think the answer
is no. So my next question then is could it be done?
