- Encyclopedia Britannica Online defines a PostScript font as a scalable (resizeable) outline font (typeface) produced by a page-description programming language. It precisely positions text and images utilizing mathematical instructions for proper display on-screen, in print or through another typesetting device.
History
- The PostScript programming language (PS language) was developed in 1984 by Adobe Systems Incorporated, based on work pioneered at Xerox PARC (Palo Alto Research Center). It communicates complex graphic printing directives to digital printers mathematically via Reverse Polish Notation (Postfix). This allows precise rendering of vector images, raster images and text regardless of the resolution or coloring process of the output device.
Type 1 Fonts
- PostScript fonts are most commonly available as Type 1 fonts. These are simple, single-byte digital fonts, referred to as "outline" fonts because they describe the outline of a glyph (character), not an actual raster image. Type 1 fonts utilize two file formats for proper rendering, the Printer Font Binary format (PFB) for glyph data and the Printer Font Metrics format (PFM) for metric (height
