About computer screen optimising (hinting)

Hinting instructions give the designer a tool to correct the way the computer displays the characters on the screen. In technical terms, the designer can manipulate the TrueType outlines prior to rasterization, specifying which pixels (the smallest ‘dot’ that the monitor can display) will be turned on or off, to ensure maximum legibility and aesthetic quality.

Most commercially available fonts were designed primarily to look good when printed: their designers have invested a lot of effort into making sure that they function well on paper, while largely overlooking how they appear on computer monitors. However, due to the relentless pace of technological change and its impact on how we work, we spend more and more time reading from the screen rather than from printed materials.

While hinting instructions provide the designer with a tremendously powerful tool, the hinting process itself is tremendously labour-intensive, particularly if the designer uses delta-hinting to hand edit each character at each point size. The amount of effort involved explains why screen-optimized fonts are relatively rare.

The examples on the right shows hinted and unhinted screen rendering of the fonts, showing that careful hinting produces fine-tuned text that is easier to read, even at small point sizes on low-resolution devices such as computer monitors and (older) laser printers. And of course, the quality of printed characters remains as high as ever.
