Postscript is a page description language with print-independent character for the output of print data. This font, developed by Adobe, uses cubic equations to calculate the Bézier curves of each character in the font.
Postscript fonts are vector-based fonts that are stored in two different files: One file includes the outline format for printers, and the other file has bitmaps for screen display. There are approximately 30,000 Postscript fonts. The vector-based Postscript format works with coordinates, polygons, lines, colors, area fills, and more. As with all vector-based representations, the basic graphic elements are specified by coordinate points, radii and angular degrees in Polish notation. In Encapsulated Postscript, color representation and document exchange are improved.
Postscript is characterized by its performance and manageable flexible command structure and can be considered as the predecessor of the PDF file format. Postscript files can be converted directly into the Portable Document Format (PDF). The file extension of Postscript files has the suffix *.ps, for the EPS file format (Encapsulated Postscript File) it is *.eps.
