PDF Emerges From PostScript

One thing that PostScript never became, however, is a universal format for file exchanges. Instead, customers send their native application file from an application like Quark or PageMaker and include the resources, such as fonts and graphics. This all goes to a prepress area where it is reassembled and converted to PostScript and passed on to a digital output device like an imagesetter or printer. This has become known as a PostScript workflow.
