Be carefull... last time I checked ColorLab the Density calculation
seemed faulty. The density value I got from ColorLab was off by more
than the typical rounding error... But that was roughly one year ago.
Maybe they fixed it by now? Or maybe they do mean a different DIN
5033 status density value?

But carefull again, there is a popular Excel sheet on the internet
that shows how to calc XYZ, Density and other values from spectral
data that is also faulty when it comes to Density calculation (wrong
cell references and more).
X-Rites ColorShop (30(?) day free trial version is available) seems
to calculate Density values fine. But I do not have the slightest
idea how to easily transfer data from MeasureTool to ColorShop
without editing/reformating the file.
But maybe you find an easy method and let us know as I often run into
this question?
