3. Optimize View on the Reader
First of all you have to understand that you’re working with a PDF file. A PDF file is not bad, it’s great, versatile, powerful and widely used, but it’s difficult to port to a different layout. Not because it’s a ‘stupid’ PDF, but because the content was optimized for this specific layout. And compared to content in ePub format or others (without any layout), the content of a PDF file is most often highly complex. So to get the best results, try to preserve the given layout.
General tips
View
Play with the settings and try the presets to see what’s possible. I personally recommend a custom setting of: (text and b/w images look much better, but some greyscale images may look worse)
Brightness -40
Contrast +40
The text gets bolder, clearer, sharper and better readable. (on the eReader screen the difference is more visible)
Reflow mode
Only use it if you work with text only PDF files without complex content. But then, you can try to get the book in ePub format already, too or try to convert it to ePub with a computer software.
Zoom
Only use it casually. If you intend to ‘crop’ a page with it, better do it on a PC
Articles
To read articles you have to use the two Column/Three Column mode. Sadly it only works in portrait mode, but it works very well. It’s not as eReader optimized as ePub files, but it makes PDF articles viewable on the eReader.
You may want to remove any white margin on a PC prior, so the font gets larger on the eReader screen.
Books
Use landscape mode to increase font size without losing the given layout. But you should also use a PDF editor on a computer to remove not necessary margins.
