Since most viewers don't understand why it's better to do all this extra process work, I took a few screenshots.

Please look at attached:

PDF options that I've tried:

1)
When I first sent the original PDF directly to Amazon, all image info was lost, while the text converted fine. This sucks because maps are gone (leaving me lost)

2)
The second one, I had to convert the PDF to be image based, (turned it into a 20 meg file) and then emailed it to Amazon to be converted. The result is much better in that the result looks like the original PDF, but as you can see, the text is not optimized for the reader and it is hard to read smaller text. Also all maps (non-standard images) were badly resized to be very small making them unusable. (bad image fidelity)

3)
The third one, which I processed using the PDF2LRF -> PNG2PDF -> Mobi Creator is the best in that it replicates the look of the original PDF (image based) and more importantly, it bypasses having to attach/ email to Amazon, wait 1 hour, transfer back, which is bad for large files > 20 megs. With PDF2LRF, everything including text/borders etc... is optimized to be more readable on ebook readers then default because the program increases the contrast for text.

Also, concerning LoveBeta's response, using the PNG viewer doesn't work too well when you have hundreds of PNG images (due to the number of pages in a PDF). Having a converted .PRC file allows you to bookmark your books while images can't be.

In summary, my basic goal is to view PDFs on the Kindle as similar as the original PDF and this is the best solution I've found so far.
