FontShop’s Slide Show: Intro to OpenType
The most recent font format emerged at the beginning of the new millennium. OpenType was initially developed by Microsoft, which were later joined by Adobe. In a few years time it has become the new standard format for digital fonts. The biggest advantages shared by all OpenType fonts are their single file structure, cross-platform compatibility, and advanced typographic functionality. This means any single OpenType font file will work on both Mac and Windows systems, and some OpenType fonts include expanded character sets and special features like automatic ligatures and alternate glyphs. OpenType is the best format for most purposes. It comes in PostScript flavour (OTF) and TrueType flavour (TTF).
