Hi Bruce,
I agree with everything you said and thought I had qualified everything
I said. However, with regard to reflective spectrophotometers I believe
that all measurements are done to an absolute standard rather than
relative. I also understand that what I said only applies to
non-fluoresent papers. I have exchanged data with many color scientists
and, with regard to reflective measurements, we have always talked about
the minimum and maximum L* values that a particular hard copy proofing
system can produce.
Can you confirm or correct this practice.
Thanks,
Ray Maxwell
