7. Select Discard User Data in the left pane of the dialog box to allows deletion of comments, file
attachments, private data embedded by other applications, and hidden layer content.
8. Select Clean Up in the left pane of the dialog box to remove unnecessary items from the docu-
ment. By default, only elements that do not affect functionality are selected. If you are unsure
of the implications of removing other options, you should use the default selections. You can
choose from these options:
•
Object Compression Options: Lets you remove all compression or compress docu-
ment structure. If you’ve chosen compatibility with Acrobat 6.0 or later, you can also
compress the entire file or leave the compression unchanged.
•
Use Flate To Encode Streams That Are Not Encoded: Analyzes if applying compres-
sion to a particular stream will reduce file size. Compression is applied only if file
size will be reduced.
•
In Streams That Use LZW Encoding, Use Flate Instead: Replaces LZW encoding
with Flate encoding.
•
Remove Invalid Bookmarks/Remove Invalid Links: Eliminates bookmarks and links
that point to deleted pages or to other invalid destinations.
•
Remove Unreferenced Named Destinations: Deletes named destinations that the
PDF document does not reference internally. Because this option does not check
for links from other PDF files or websites, it may not fit in some workflows. As with
links and bookmarks, deleting these aspects of the PDF may impair navigation when
viewed on screen, but has no adverse effect on imaging.
•
Optimize The PDF For Fast Web View: Restructures a PDF document for page-at-
a-time downloading (byte-serving) from web servers. This option has no benefit for
printing, so it can be set on or off.
9. Click OK, name the new optimized PDF file, and specify a location for it. The original PDF
document remains unchanged.
For information on specific PDF Optimizer options, see Complete Acrobat 9 Pro Help, available
in the Help menu.
Using the Job Definition Format (JDF)
Keeping track of a job’s specifications, especially on a complex job, can be challenging. Job
Definition Format (JDF) provides a streamlined way to create an efficient, automated workflow
based on Adobe PDF. The features in Adobe Acrobat 9 Pro enable you and your customers to cre-
ate JDF files on the desktop to preserve information that can be used later in the workflow.
About JDF files
JDF is a job-ticketing file format that provides a mechanism to specify and control all of the
processes in print production, from job submission through prepress, press, and postpress. As a
device-independent standard, JDF can describe every part of a job (cover, inside pages, binding,
number of copies, and so on) and link management information systems (MIS) with production
workflow systems—no matter what tools are used. JDF places individual actions into a greater
context, so that each element is recognized as part of the whole. In the same way that Adobe
PostScript describes pages and Adobe PDF describes documents, JDF describes jobs.
Acrobat 9 Pro JDF files include product information, such as job ID, number of copies, binding
settings, and customer information; section data for each section of the job, such as the section
name, number of pages, page size and orientation, scaling percentage, and inks; and file data for
each native or PDF file assigned to a section, including the file name, document name, and page
range. You can add more job data to JDF files as more information is obtained about the job’s
specifications. You can create a high-level JDF file that describes only a rough outline of the job;
as you add information, the outline can evolve into a detailed product description.
You can embed PDF creation settings (.joboptions files) and preflight profiles in a JDF to ensure
the integrity of the files before the job enters print production. Acrobat 9 Pro compares the job
description with the properties of the assigned files and reports any discrepancies in page size,
inks, or the number of pages available in the associated documents.
