Caecilia, used on the Kindles and Nooks is well-designed for a serif reading speed-font on the moderate resolution of current e-ink screens. PRS+ does a great job of allowing us set font and type size, and I use Caecilia in various sizes to set the line and character size.

However, at smaller sizes on my PRS-950, it seems a bit low-contrast to me, with too-thin strokes, so I've been looking for a darker (bolder) alternative. After B&N upgraded the rendering technology on the Nook Simple Touch, they delivered a slightly darker version of Caecilia, which I found more satisfactory than the Amazon rendition, and that's been my goal.

So here is my bolder version of Caecilia for PRS+. I think it is pretty close to the Nook Touch rendering.

I simply used Caecilia Bold 75 for the base font, and Caecilia Heavy 85 for bold type. This delivers a higher-contrast rendition than the Standard weight, and makes smaller sizes much more readable - almost like a higher-contrast e-ink screen. Bold Italic 76 and Heavy Italic 86 provide for the other two combinations.

Here's the .65em CSS file. I renamed the .otf font files to remind me what was in them, and then saved a series of CSS files in sizes from .65em to 1.00em (.65em, .70em, etc.). I select the CSS file based on the filename, and get the size I want.

(I also tell calibre to set .3em paragraph spacing, left-justify, and remove all other fonts when I prepare the file for sideloading.)
