EPS: Encapsulated PostScript
A vector file requiring PostScript language to draw its image. You must have a specific software application to create an EPS file, such as Adobe Photoshop, Adobe Illustrator and QuarkXpress. EPS file is often used when exchanging vector graphics (e.g. logos) that are only to be read but not edited by the receiver, such as sending the file to a print house. An EPS is really a collection of several other image files all in one. EPS files are generated from several sources and are structured to published code constraints. An EPS file has two main parts: The Preview The high resolution image data The preview of an EPS file is necessary to display the image in a page layout application, and the high-resolution portions of the file are necessary for imaging to a particular output device. When you embed (Encapsulate) graphics in a document it is therefore called Encapsulated PostScript or EPS.
