Font hinting is the process of adapting an outline font to a rasterised grid, critical for producing clear legible text for on-screen text display.

The TrueType format was jointly developed by Apple and Microsoft in 1991, several years after the release of the PostScript Type 1 font format. Despite the format’s technical superiority (most of the system fonts on both Mac and Windows computers are TrueType) it never became popular amongst designers.
PostScript or Type 1 fonts were developed by Adobe in 1985 for use with their PostScript printers. Initially, this font technology was available only from Adobe.
