PDF And You

• PDF is a file format that relies on PostScript for imaging.

This is a critical distinction, as some people thought that PostScript would "go away" once PDF took hold. On the contrary, PostScript will stay right where it was always intended to be: in the background, acting as an interface between the digital design and its presentation on paper, film, plate or screen. What is more likely to disappear is EPS—encapsulated PostScript.
