[argyllcms] Paper White

Hi 

I see that many manufacturers of paper gives CIE values of the paper whiteness.

I thought that this was CIE LAB but it seems to be something else

As I have tried to measure a paper that had a L value of 96 but the 
manufacturer gives a CIE value of 126 for the same paper.

How is this measured?

Is it possible to measure in Spotread somehow?

Best regards
Amin
