You can use Vuescan software to obtain log density values directly. However
it has been my experience with several different Epson scanners as well as a
couple of Microtec scanners that the DMAX ratings are way way over inflated.

IMO, you are wasting your time trying to do serious densitometry without a
densitometer. A good used XRITE 810 isn't that expensive.

Good luck,
