The free program Irfanview will create negatives of PDF documents. It seems to work ony one page at a time, but perhaps there's a batch mode I didn't see.

What started all this was the lack of 'night mode' function for pdf files on my Kindle Fire. Until now, all previous responses to this situation over in the Kindle Help Forum stated that, the device's night mode function (as well as a few other functions) could not do this for pdf books. Hence my efforts and this post. TODAY, I just learned that Amazon offers a free Adobe Reader app for my device. That's it! Game over!
thnx all.
The kindle fire uses a mocked up/customized (by amazon) version of android and amazons appstore. They have the more popular stuff, but not everything from google play.
Glad you got it working :)
Wished we had known that the reason for reverse printing was for easier reading on a Kindle. Might have got to the solution much sooner! Still glad it'd sorted.
