Hello all, M1 is D50 measuremnt with a defined UV part in the measuremnt lightning and M2 a measuremnt with No UV in the measuremnt lightning. A comparison of M1 and M2 measurements gives a clear indication of the amount of OBA / FWA in the measurement probe. regards Jan-Peter Am 10.12.14 12:08, schrieb Graeme Gill: > robert@xxxxxxxxxxxxxxxxxx wrote: > > Hi, > >> As you are doing a new release, I don't suppose you would be able to add an >> option for the i1Pro2 to measure UV on / off for spotread? > No, that's a major amount of work, and I don't see having time > for it at the moment. > >> i1Profiler has >> this feature and it's very useful to get an estimate of how much FWA is in >> the paper (for example, with a particular paper the b* reading is -15 with >> UV and -4 without ... which gives a good indication of very high FWA >> content).
