Introduction
Adobe Acrobat®software helps you create content for the Internet that is compact,
graphically rich, interactive, intuitively navigable, and easy to publish. Portable
Document Format (PDF) publishing on the Internet unshackles your creativity
from Web-specific publishing applications and allows you to use the almost limit-
less design capabilities ofto-day’s powerful print-publishing software.Ifan appli-
cation can print,it can be used to create compelling content for the Web.
The World Wide Web introduced most people to Adobe Acrobat and PDF files—
and still does. Early in the growth of the Web, Adobe recognized the value of
Acrobat and PDF files as a solution for publishing visually complex information
on the Internet.PDF files exhibit a number ofcharacteristics that make them well
suited for the Internet:
n They are cross-platform binary files,requiring no translation or conversion
when moved among popular platforms,such as Windows,Macintosh,
UNIX,and other operating systems.
Introduction 3
n PDF files are surprisingly compact (in file size) for the
amount of visual and contextual content they contain.
n They support text,graphics,and other media formats.
n PDF files are interactive and navigable.
To encourage the use of PDF files on the Internet,Adobe regis-
tered the PDF file type as a standard file type (like JPEG graph-
ics and HTML files) for use on the Internet. Adobe published
the specification so that others could develop software that uti-
lized the PDF technology. With this evolution of the Acrobat
technology,a Web browser could be configured to automatically
launch the freely available Acrobat Reader as a helper applica-
tion and open a PDF file after it was downloaded. Adobe’s
Weblink plug-in—an add-on module formally introduced with
Acrobat 2.1—enabled Reader (and Acrobat Exchange) to com-
municate with most Web browsers.This communication allowed
authors to create links from PDF files to other sites and files on
the Web—the same way links are used in HTML documents.
Acrobat 3.0 (originally code-named Acrobat Amber) takes this
link in communication among the Web, PDF files, and Acrobat
one step further.Acrobat 3.0 integrates the relationship between
Web browser and Acrobat Reader by enabling the Web browser
to display the PDF file within the Web browser’s document win-
dow (usually reserved for HTML and image files). Now when
viewing a PDF file,the basic Acrobat toolbar appears so the user
can navigate and interact with the PDF file as if it were being
viewed in Acrobat Reader.
Historically, Web publishers shied away from PDF files, feeling
they were simply too large to be useful for publishing on the
4 Chapter 1
limited-bandwidth Web.Originally,PDF files were developed for
local access networks or large internal networks (intranets),
which typically had much greater bandwidth capabilities than
the average Internet user.PDF files also can be large because of
the types of documents that are published as PDF files.Authors
and designers creating PDF files wanted to preserve exactly the
electronic magazines,newsletters,technical drawings,and other
visually complex documents with their original fonts, extensive
use of color,images,graphics,and other design elements.These
features included all the attributes that publishers had come to
expect from modern page layout, design, and word processing
software applications—including large file size.These files had to
be completely downloaded before they could be viewed.
Ironically,history has shown that PDF files are not significantly
larger than HTML files and are sometimes smaller or the same
size as most comparable HTML designs.
Adobe Acrobat 3.0 allows the publication of even smaller PDF
files than previously thought possible through new compression
schemes.Now with Acrobat 3.0,PDF pages render as each page
element is downloaded, in much the same manner as HTML
files;and,only the pages requested are downloaded—no need to
wait until the entire file has downloaded before it can be viewed.
This allows PDF pages to be viewed as fast or faster than most
image-heavy HTML files.
PDF files are the portable document file format of choice for
hundreds of companies that publish documents on the Internet.
Other companies also use PDF files as the file format of choice
when distributing information via intranets,CD-ROMs,private
computer networks, floppy diskettes, and other media formats.
About This Book 5
PDF files also are the document format of choice for electronic
magazines, technical documentation, books, marketing docu-
ments,catalogs,readme files,white papers,and other document
types that need to be distributed via various computer platforms,
operating systems,media formats,and networks.
From a publisher’s perspective,little experience beyond the skills
of most print publishers is required for producing PDF files.
Every major desktop publishing software package and a number
of graphics applications support the PDF file format.Publishing
content as PDF files requires no new design training,as HTML
did. Many of these software applications have additions, plug-
ins, macros, or other utilities that quickly and simply convert
document information such as tables of content, cross-refer-
ences, and notes into intuitively navigable and interactive PDF
file objects. Creating PFD files is easy. This book will help you
publish PDF files expertly.
About This Book
1.1
Internet Publishing with Acrobat is the essential reference guide
for publishers ofPDF files on the Internet,or those who want to
publish PDF files on the Internet.This book is both a technical
reference and a content development guide.It contains the most
comprehensive technical information about Acrobat and
Internet publishing available to date. Much of this information
comes directly from Adobe engineers working on Acrobat, and
countless third-party developers, power users, and experts.
Unlike the plethora ofbooks on HTML and Web publishing,and
the handful of books on Acrobat, this book provides the infor-
6 Chapter 1
mation necessary to determine how best to serve content: as
Portable Document Format (PDF) files,or as Hypertext Markup
Language (HTML) files. Many of today’s Internet sites created
using HTML are ineffective and could benefit dramatically from
the addition and integration of PDF files. Internet Publishing
with Acrobat provides the knowledge a publisher needs to seam-
lessly integrate PDF and HTML files at both the document and
site-wide levels. The efficient exposition of technical informa-
tion—often compactly in tables or figures—will help the
Internet publisher determine the most appropriate Acrobat tool
to create compelling PDF files for various document types.The
combination of detailed technical information and content
development solutions will answer questions,while opening up
new content publishing possibilities.
Rather than recycling and repeating the information found in the
numerous tutorials, user guides, books, magazine articles, and
online discussion groups that focus on using Adobe Acrobat,this
book concentrates on what the publisher needs to know to devel-
op content for the Internet.Ifyou are new to Acrobat,you’ll find
yourself referring back to Adobe’s documentation and user
guides.Ifyou have limited experience working with HTML files,
you may want to take a tutorial in HTML markup before delving
into some ofthe more complex information found in later chap-
ters. This book lists numerous resources for Acrobat-related
issues. So if you’re not familiar with a topic or concept, you’ll
know just where to look for more information. Internet
Publishing with Acrobat has been carefully focused to provide
Internet publishers with exactly what they need to expertly pub-
lish PDF files on the Internet with Acrobat.
Using This Book 7
Internet Publishing with Acrobat covers Adobe Acrobat 3.0, a
major update of the Adobe Acrobat family of software.Acrobat
3.0 includes a number of new Internet-specific features and
enhancements that make publishing with Acrobat more efficient
and exciting than ever.However,even users of previous versions
ofAdobe’s Acrobat software (2.1,2.0,or 1.0) will benefit from the
technical information and content development strategies
described throughout this book.
Most of Acrobat 3.0’s features have been added or enhanced to
make publishing and using PDF files on the World Wide Web
faster, easier, and more compelling. The Web is by far the most
popular service on the Internet. However, rather than limiting
the scope of this book to the Web, this book encompasses the
whole Internet to include information on sending PDF files as
email attachments and serving PDFs on FTP and Gopher sites.
There’s also technical information and content service strategies
and solutions for publishing PDF files on intranets and on-
demand print servers that use servers, applications, and applets
to generate PDF files dynamically. These non-Web server and
distribution strategies offer additional publishing opportunities
alone,or in conjunction with Web publishing efforts.
Using This Book
1.2
Put this book near your computer.Undoubtedly,you’ll refer to it
as you create, design, edit, and prepare to publish PDF files on
the Internet. Use this book before you choose a page size, for
example; or, refer to it after you’ve sent your completed docu-
ment to the printer,and now want to publish it on the Web.You
8 Chapter 1
may want to keep this book with your favorite book on HTML,
a book on Java, your server’s user manual, or some design
books—all within easy reach.
The best way to use this book is in conjunction with the Acrobat
user guide. The user guide includes much of the how-to infor-
mation you’ll need to perform the actions referred to in this
book.In many cases,actual sections of the user guide are repli-
cated so you can quickly find solutions.Also,the user guide has
non-Internet publishing-related information,how-tos,and trou-
bleshooting that may prove useful when creating, converting,
and publishing PDF files with Acrobat.
The tasks and concepts involved in Internet publishing with
Acrobat borrow from a number ofdisciplines.You should refer to
a good book or tutorial on HTML ifyou haven’t published many
HTML files. Knowing the basics of HTML will help you better
integrate HTML with PDF files.For additional information about
related Internet-publishing technologies,see Chapter 10,“Acrobat
Resources,” for lists of books, publications, recommended Web
sites, and discussion groups. The more you experiment with
Acrobat and the more you explore the publishing possibilities of
Acrobat and PDF files,the more useful you’ll find this book.
Internet Publishing with Acrobat is organized sequentially, with
each chapter comprising one of the major steps in the Internet
publishing process.Chapters and sections are numbered for easy
reference. Tables condense highly-technical information into
easily digestible chunks,and figures simplify technical concepts.
Using the book should be no problem.You may, however, have
some questions about how the information is presented in this
book and what you will find.
