In-Depth Information
While it is up to the user to determine which settings are best for each use case, here are some starting
points:
x General. Compatibilityshould be set to Acrobat 6.0 or later. Object Level Compression should be set to
Maximum and resolution to no less than 300 dpi. Optimize For Fast Web View should be set if the file
is multiple pages and intended for the Web. Fast Web View does not add to speed of a single page file.
x Images. For color and gray-scale images, turn Downsample off and set pixels per inch to no less that
300. Compression should be set to JPEG or JPEG2000. There have been reports of display speed
problems with JPEG2000 on versions 6 and earlier, so you may want to try both compression methods.
In general, a compression quality of Medium or High will give acceptable results.
x Fonts. Check both the Embed all fonts and Subset embedded fonts at 100%. Distiller requires that you
have permission to use fonts before it will embed them, so be careful in your font choices.
x Color. Unless you are knowledgeable in color management, it is suggested that you choose the Leave
Color Unchanged option.

Case Study One: Creating PDF Maps using ESRI ArcMAP
Currently, the most commonly used software for electronic map production is ESRI ArcGIS, using the
ArcMAP extension. ArcMAP allows users to set up map frames and systems of maps and then output
directly to PDF using the Export map command. Many ESRI users are beginning to use this feature to
distribute their map data to their non-technical customers.
The city of Burnaby is a small (40 square mile) but growing municipality west of Vancouver, Canada.
Its Engineering Systems group provides mapping data to departmental users and citizens, originally in
manually drawn form and more recently through an automated ESRI GIS.
