Online Versus Print (cont.)
Portable
Document Format
The portable
document format (pdf) is a file format designed to address some particular
problems brought to publication by the digital age.
The pdf
offers consistency and universality for presentation of content, independent
of native file format and source—that means, regardless of whether the original file was produced on a Mac or a PC, or whether it was produced in Microsoft Word, Adobe Pagemaker, or Macromedia Freehand.
By 1993,
Adobe had identified a problem in the document world. You may have
discovered this same problem in your world of document production.
When you have invested careful effort in producing a perfect document,
perhaps one with extensive formatting,
charts, graphs, and
pictures,
the details of the formatting can be lost as soon as the document
is passed on to another user on another machine or who has a different
printer.

Sometimes
it seems to you and it seemed to the developers
at Adobe that the only way to guarantee the fidelity of presentation
is/was to print the document and distribute hard copy.
Though printing
out copies of a file seemed to undermine the whole reason for having
electronic documents, it seems/seemed like digital file exchange is
simply not reliable.
In 1993,
the original Adobe Acrobat plan was to translate PostScript files into
page-oriented, resolution independent, exchangeable (or portable) documents,
viewable an any computer platform and unaffected by the associated
printing device.
