I am specially preparing some PDFs for use on E-ink devices. I have noticed that the appearance of the text on these screens is not exactly the same as the appearance on a book, or the appearance on a computer screen. Are there any strategies for selecting fonts which will appear good and improve readability on these devices?
As far as I am concerned the effect of low resolution on e-ink screens is quite similar to the appearance of the newspaper where low-quality paper with high soaking ability tends to distort fine details of letter shapes.
So I would probably recommend the same typefaces that are used for setting the text in newspapers - low-contrast, with thicker serifs and larger counters - something like ZÃ³calo Text, Swift, PF Adamant etc.
