PostScript fonts
type of font files encoded in outline font specifications developed by Adobe Systems for professional digital typesetting
PostScript fonts are font files encoded in outline font specifications developed by Adobe for professional digital typesetting. This system uses the PostScript file format to encode font information.
PostScript fonts may also separately be used to refer to a basic set of fonts included as standards in the PostScript system, such as Times New Roman, Helvetica, and Avant Garde.
History
Type 1 and Type 3 fonts, though introduced by Adobe in 1984 as part of the PostScript page description language, did not see widespread use until March 1985, when the first laser printer to use the PostScript language, the Apple LaserWriter, was introduced.
Even then, in 1985, the outline fonts were resident only in the printer, and the screen used bitmap fonts as substitutes for outline fonts.
Although originally part of PostScript, Type 1 fonts used a simplified set of drawing operations compared to ordinary PostScript (programmatic elements such as loops and variables were removed, much like PDF), but Type 1 fonts added hints to help low-resolution rendering. Originally, Adobe kept the details of their hinting scheme undisclosed and used a (simple) encryption scheme to protect Type 1 outlines and hints, which still persists today (although the encryption scheme and key have since been published by Adobe). Despite these measures, Adobe's scheme was quickly reverse-engineered by other players in the industry. Adobe nevertheless required anyone working with Type 1 fonts to license their technology.
Type 3 fonts allowed for all the sophistication of the PostScript language, but without the standardized approach to hinting (though some companies, such as ATF, implemented their own proprietary schemes) or an encryption scheme.

Why this record matters
A short description can identify a subject without explaining its stakes. For “PostScript fonts”, the useful work is to connect “type of font files encoded in outline font specifications developed by Adobe Systems for professional digital typesetting” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q785247. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1984 and 1985.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
