Understanding File Types

Each zip file containing the different configurations of the logo contains three file types: EPS, JPEG and PNG.

(Encapsulated PostScript file) is a vector format. It can be re-sized without losing image quality. It is the best choice for anything professionally or screen printed.

(Joint Photographic Experts Group) is a raster file widely supported and works in almost any program. It is best used in common things like invoices, page layouts, or letterheads. Please use this file type for Microsoft Word.

(Portable Network Graphics) is a web-based file that does not lose quality when compressed. PNG files are best used for the web or computer-based designs and maintain a transparent background.
