You can either get a spectrometer to measure the various materials 
scanned. Or you could use spectral imaging. For instance, have a look 
at the IEC 61966-8:2001 standard ("Multimedia colour scanners"). 
There is even a test-software available for this standard freely 
somewhere online. I am eager to hear from practical results as I am 
thinking about adding support for this standard....
