PostScript
PROS:
• Industry standard PDL (page description language)

• Device-independent (a.k.a. resolution-independent)

CONS:
• Files to be saved as PostScript must include all fonts and graphics (but frequently don't)

• Neither editable or page independent (corrections must be made in "native" application, then entire file must be re-RIPped)

• Different applications generate PostScript code in different ways

• RIP A may process PostScript differently from RIP B

• Can't display documents for on-screen viewing

PDF (Portable Document Format)
PROS:
• PDF files can be created, viewed, and edited by anyone, anywhere with Adobe Acrobat software

• No more worries about missing fonts or graphics

• Converting PostScript to PDF "normalizes" the PostScript code, making it consistent and predictable

• PDF files are editable (up to a point) without re-RIPping

• PDF files are page-independent--individual pages can be processed on multiple RIPs that support PDF input

• PDF files are "repurposable" for print, CD-ROM, the Web, etc.; "the pages always look the same"

CONS:
• PDF is still not the industry standard that PostScript is...but stay tuned
