C H A P T E R T H R E E Creating PDF Files in Distiller and Acrobat

Don’t Use Page Ranges
The General tab includes an
option for selecting a specific
range of pages. Don’t enable
this option unless you’re sure
the custom settings are for
onetime use. If you specify
a range of pages when you
create the job options and
then reuse the settings
another time, you convert
only those pages specified
in the General tab. This can
lead to time-consuming
troubleshooting when you
use your custom settings and
can’t figure out where your
pages have gone!
content. O leaves the document’s structure as is; the Tags Only option
compresses structural information in the PDF document. Compressed
information is viewable only in Acrobat 6 and newer; leaving the
option set to O allows structure and tagging information to be usable
in Acrobat 5 as well.
•
Resolution. You can set this option to emulate the resolution of a
printer for PostScript les. A higher resolution usually produces higher-
quality but larger les.
•
Embed thumbnails. Thumbnail previews are used for navigation,
and have been created dynamically since Acrobat 5. Don’t enable this
option unless you are using very old versions of Acrobat; it adds to the
le size unnecessarily.
•
Optimize for fast Web view. Choose this setting if the le is intended
for online use, or distribution via e-mail or a server. An optimized le byte
serves the content, breaking it up into chunks a page at a time, letting the
user read as the le is loaded rather than waiting for the entire le.
In the Images dialog, you may need to adjust and test setting changes
several times for converting les with complex images. Consider these
options:
•
Downsample. Pixels in images with a resolution above a specied
amount are combined to reduce the resolution. You may want to
increase or decrease the downsampling level. For images such as maps
(where the user zooms in to a high magnication), a high resolution is
much more legible.
•
Compression/Image Quality. Select options depending on the le’s
color, or if you have grayscale or monochromatic images.
•
Anti-aliasing. Smooth jagged edges in monochrome images by turn-
ing on anti-aliasing.
•
Policy button. Click this button in order to specify how to process
images when they are below the resolution you dene. You can specify
whether to ignore, warn, or cancel a job based on the resolution of
color, grayscale, and monochrome images. Setting policies can save
you processing and reprocessing time in the event the images in a le
don’t use the correct resolutions.
