the patch with the lowest chroma
I agree with Todd Shirley on this one and would attribute the success
of this to circumstance. I can't see how measurement is going to
consistently agree with visual analysis with substrates with varying
amounts of optical brighteners, hence the point of the visual analysis
in OBC. Visual analysis would be more subjective, but given that
there isn't a fool proof method for quantifying the amount of optical
brighteners in paper with current instrumentation, and that ambient
lighting is totally neglected in measurement, I can't see this being a
solution that works in all circumstances.
