Appendix E. Encapsulated PostScript File v.3.0 vs. PostScript File Format

In the course of maintaining your system, you are likely to receive files in various versions of the PostScript format. Following are some of the main differences between the Encapsulated PostScript File (EPSF) version 3.0 format and PostScript file format:

The EPSF format was designed for importing the PostScript description of a single page or part of a page, such as a figure, into a document, without affecting the rest of the description of that document. EPS code should be encapsulated, that is, it should not interfere with the PS code that may surround it, and it should not depend on that code.

The EPSF format is usually used for the output from a program that was designed for the preparation of illustrations or figures, (such as Illustrator) and as input into desktop publishing programs (such as Adobe Systems FrameMaker). Most desktop publishing programs can produce the description of a document in the PostScript format that may include the imported EPS code.

For more information about these formats, see the book PostScript Language Reference Manual, Second Edition, Addison-Wesley Publishing Company, Inc., Reading, MA, 1990. You can get several documents on the EPS and PS formats from the Adobe Systems PostScript file server by entering the following at a UNIX prompt, and then following the instructions you get from the file server:
