I see that many manufacturers of paper gives CIE values of the paper whiteness.
How is this measured?
See <http://www.axiphos.com/BrightnessReview.pdf> for a good explanation of this.
Is it possible to measure in Spotread somehow?
No, I haven't put specialized measurements such as density and whiteness in there. Whiteness uses a particular narrow band filter. If you are using the paper for proofing purposes, then I think that CIE whiteness is not very useful, and that looking at spectral shape, delta E and level of FWA is probably a better way to evaluate matches between papers.
