- Description
 - PostScript Type 3 consists of glyphs defined using the full PostScript language, rather than just a subset. Because of this, a Type 3 font can do some things that Type 1 fonts cannot do, such as specify shading, color, and fill patterns.
 - A PS file is an image saved in the PostScript page description language. It may contain vector graphics, raster graphics, and text. PS files can be printed directly by a PostScript printer (i.e., containing a Raster Image Processor) without being opened in an application.
