Learning about Fonts Hinting

Postby Orbmiser » 23 Jun 2014 23:17

Don't know if right place? But an informative about fonts,rendering and LCD screens.

Font hinting
https://www.typotheque.com/articles/hinting
Hinting, or screen optimising, is the process by which fonts are adjusted for maximum readability on computer monitors. I have been designing type since the early 1990s, and for as long as I can remember, type designers have been saying that hinting would soon be made obsolete by new advances in hardware and software. Now, almost 20 years later, hinting seems to be more relevant than ever.

The problem is that typical modern fonts are not designed primarily for the 72–96 dpi resolution of computer screens, but for the much higher 1,200+ dpi resolution of print media.
This is exactly what hinting is about: programming instructions that fine-tune a font’s rasterisation, the process by which its mathematically ideal outlines are mapped onto a monitor’s pixels. Hinting can control the heights and widths of a font’s uppercase and lowercase letters, the widths of its individual lines, the amount of white space around letters, the size at which uppercase letters start to use different stem-widths from lowercase letters, how the angle of italic characters changes to best fit the pixel grid, and many other extremely technical details, all on a pixel-by-pixel basis. If this sounds like a rather tedious, time-consuming activity, it is, (even for type designers, who are accustomed to tedious, time-consuming activities).
Hope something useful in there explaining the difficulties with fonts and rendering on LCD screens.
