The eps (Encapulated Post Script) file format is used to transfer a graphic image between applications and platforms. EPS files contain PostScript code as well as an optional preview image in TIFF, WMF, PICT or EPSI, the latter being an ASCII-only format. An eps (as vectors) is the most reliable way to send a graphic image to an end user ie signwriter, graphic designers, press etc. Usually, only industry professionals are able to open or import eps files. When supplied as an eps, artwork can be enlarged without loss of quality, recoloured, pulled apart and modified in many ways.
