Adobe's PostScript (.ps) format is the standard
in printing. The newer Adobe Acrobat Portable Document
Format (.pdf) is essentially optimized PostScript,
so like PostScript it preserves the exact look and
positioning of all your document's parts, while producing
much smaller files than PostScript. These documents can
be viewed on-screen at various magnification levels, or
printed on any printer. You can choose to embed the
fonts you used for absolute fidelity, or produce
smaller files that will still preserve all spacing and line-breaking,
while substituting standard fonts available on the user's
computer.
Acrobat was one of the first formats to support hyperlinks
between and inside documents. Acrobat bookmarks provide
an easy, intuitive table-of-contents including document
navigation. Page elements can be active links as well, or
they can be used for launching multimedia. You can even
create fascinating slide presentations in Acrobat, both
self-running or with in-document navigation links.
