PostScript - What is PostScript?
A computer language developed by Adobe that is commonly used in desktop publishing software to create vector graphics. PostScript is a type of page description language, which means that, essentially, it describes pages, including the objects on each page and the specific layout of these objects on the page. As an object-orientated and vector-based language, PostScript treats all of the content on a page (including images and fonts) as objects that are created from geometric lines and shapes according to mathematical equations. This means that these documents are resolution independent; when the document is opened and/or printed, the elements are created according to the instructions in the file (the geometric shapes and lines and mathematical equations) and so can be created using the highest possible resolution available (unlike bitmap graphics, which are created with a specific resolution that cannot be adjusted later on). PostScript, therefore, is popular with desktop publishing software as it is supported by high resolution laser printers and imagesetters (which are used by professional printing services).Go Back to Glossary
