Inverted E Ink: Reading with White Text and Black Background on Nook Touch
Ever since I rooted my Nook Touch I’ve been experimenting with various apps, trying to find new ways to use the Nook and different ways to read.
Here lately I’ve grown fond of using night mode to reverse the usual black text on a white background to white text on a black background.
With paper books something like that would never work because the amount of ink required to blot out everything but text would be considerable, and pricy. But with electronic ink, E Ink microcapsules can be turned to either black or white, it makes no difference, the old dictates of printing need not apply.
The Aldiko Android app works well for this. That’s it shown in the picture above (bonus points if you can figure out which book I’m reading). Night mode with the Kindle and Nook Android apps, however, doesn’t fair as well: the white is not bright enough, it’s too grey. The Google eBooks app and ezPDF Reader app both work well for night mode, though, but the latter only offers night mode when using text re-flow.
Night mode wasn’t designed for this, of course. It is meant for backlit screens so that reading at night doesn’t put out so much light with the usual white background. With an E Ink screen no light is being emitted so it still needs a light for reading at night just the same.
As far as I know, the rooted Nook Touch is the only dedicated E Ink ebook reader that can do this since it is the only one that can be hacked to run Android apps (hopefully the Sony PRS-T1 is the second). No other ebook readers have a setting to switch to a black background, but maybe they should. Reading with a black background is a nice change sometimes.
And in case you’re wondering, no, the Nook Touch doesn’t normally have landscape mode. But most Android ereading apps have an option to switch to landscape. The Nook Touch is so comfortable to hold in landscape mode, it’s a shame that Barnes and Noble didn’t include it with the Nook’s stock reader app.
