The EPS (Encapsulated PostScript) format is widely accepted by the graphic arts industry for saving images that will be placed into programs such as Adobe Illustrator® and QuarkXPress™. It is used on both the Mac and PCs. It was originally created as an output format for printing images. The EPS format is usually used for vector files but can also be used for raster files. One reason to use EPS in an image editing program would be to save duotones, as they can only be saved as EPS. If you are using bitmap mode, the EPS format allows you to save the white areas of your image as transparent areas. The EPS format is also used if you are saving an image with a clipping path.
