I was assuming that the white calibration tile supplied with the
device really was "white".
Creating white tiles that measure L=100 is highly problematic, due to the artificial whiteners involved. It is typical for the white tiles of even laboratory-grade devices (that cost more than my car) to be in the low nineties.
I assume it must calibrate to "90% white".
It calibrates to whatever tile it is trained to at the factory. There is a much more laboratory-grade device there which reads the white tile, and defines a value for it. The PrintFIX PRO spectro then reads the same tile, and calibrates to this factory value. This is, pretty much universally, how any device is trained to a white tile before being shipped.
