EPS（英文全称：Encapsulated PostScript）是PostScript的一种延伸类型。多用于单镜反光相机。

EPS（Encapsulated PostScript）是印前系统中功能最强的一种图档格式，矢量及位图皆可包容，矢量图形的EPS档可以在Illustrator及CorelDraw中修改，也可再加载到Photoshop中做影像合成，可以在任何的作业平台及高分辨率输出设备上，输出色彩精确的矢量或位图，是做分色印刷美工排版人员最爱使用的图档格式。

EPS格式的缺点是文件通常相当大，而且除非使用PostScript打印机，否则只能印出低分辨率的预视档或根本印不出图形。万一真要在不支持PostScript的输出设备上输出EPS档，唯一的方法是先使用RIP（Raster Image Processor）程序将其转换成位图格式，再打印。

Encapsulated PostScript (EPS) is a DSC-conforming PostScript document with additional restrictions which is intended to be usable as a graphics file format. In other words, EPS files are more-or-less self-contained, reasonably predictable PostScript documents that describe an image or drawing and can be placed within another PostScript document. Simply, an EPS file is a PostScript program, saved as a single file that includes a low-resolution preview "encapsulated" inside of it, allowing some programs to display a preview on the screen.
