Can you describe where these CIELab values came from? They are labeled as PMS123, but they plot as a slightly casted grey...quite far from the Pantone+ published Lab values. Just curious.
I believe the difference is because of the paper stocks. This of course will have some bearing on the grey you mention med.
Nevertheless, it still is an apple to apple comparison.
Pantone needs to regenerate their product. It is quite obvious after all this time.
Thanks,
