EPS

EPS

Encapsulated Post Script (EPS) is a normal document which has extra features to allow it to store images as a graphic file format. These files were the base for an early version of Adobe Illustrator Artwork format. EPS files have a set of data in the header which allows previews of the image which makes it easier to see what the file is before you open it. This can take a long time to render the information in the Post Script (PS) and has only recently been achieved

Apple Macintosh computers use to be the only computers that used EPS files but they could not simply render the information. This problem was solved by using the ‘fork’ system in a Mac which allows two files to be moved as though they were one. The information (PS) about the image was in one file and the actual PICT image was in the other.Although this worked on Macs, this system did not exist in other operating systems such as Windows. In order to make EPS available to other systems, Adobe added a TIFF file into the header of the PS which allowed an image to be saved. This still caused a problem for computers. Since part of the information for the image was now in a separate file, printers could not find the data in the PS. Printing appliances has to be updated so that they were compatible with EPS files.
