PostScript fonts are outline font specifications developed by Adobe Systems for professional digital typesetting, which uses PostScript file format to encode font information.
With Type 1 fonts, glyphs are described with cubic Bézier curves (as opposed to the quadratic curves of TrueType), and thus a single set of glyphs can be resized through simple mathematical transformations, which can then be sent to a PostScript-ready printer. Because the data of Type 1 is a description of the outline of a glyph and not a raster image, Type 1 fonts are commonly referred to as "outline fonts". For users wanting to preview these typefaces on an electronic display, small versions of a font need extra hints and anti-aliasing to look legible and attractive on screen. This often came in the form of an additional bitmap font of the same typeface, optimized for screen display. Otherwise, in order to preview the Type 1 fonts in typesetting applications, the Adobe Type Manager utility was required.
Type 1 font for Windows Operating System consists of .PFM and .PFB files.
