Embedding an Audit Trail
The ability to embed an audit trail in a PDF is based on the Ghent
Working Group Standard for preflight tracking. You must run a full
preflight profile (not a single check or fixup) in order to embed an audit
trail. To embed a description of the preflight profile used, as well as a
digital signature, choose Embed Audit Trail from the Preflight panel.
This provides a method for checking the document at later stages of the
workflow, to ensure that nothing has been altered after the preflight.
Preight Audit Trail
Embed an Audit Trail in a preighted PDF to help keep track of the preight results and the
prole used. e Audit Trail feature will also reect whether the PDF has been altered since
the audit trail was embedded.
PDF Fixups
When Fixups are included in a Preflight profile, Acrobat will
automatically repair specified problems that the preflight process finds.
Keep in mind that not all problems can be fixed in Acrobat. For
example, image content of insufficient resolution can be pinpointed
with Preflight, but there’s no way to rectify such an issue within Acrobat.
As with many problems in a PDF file, the origin of the issue lies much
further upstream in the lifecycle of the job. Obviously, it would be
necessary to locate a high-resolution image, replace the low-resolution
content in the original application, and generate a new PDF.
A profile may contain a preflight check, a fixup, or both. To identify
what components a profile contains, examine the icons to the left of the
entry in the Preflight profile dialog box:
•Preight proles which contain only checks will display a highlighted
magnifying glass ( ) to the le of the name.
•Fixups display a highlighted wrench ( ) to the le of the name.
•Proles that combine checks along with xups will show both the
magnifying glass and wrench highlighted ( ).
Single Checks and Fixups
Acrobat X Pro includes Single Checks and Single Fixups to streamline
the finding and fixing of common problems, such as image resolution.
Single Checks and Single Fixups can be run independently without
needing to be incorporated into a Profile. Acrobat X Pro includes an
extensive list of Single Checks, including checks for ink coverage,
transparency, font embedding, text using rich black, black objects set to
knock out, objects using Registration color, images below a threshold
resolution, and many more. Single Fixups include convert Registration
color to black, merge spot colors with different names, embed fonts,
assign object types to layers for troubleshooting, and much more. You
can also create your own Single Checks and Single Fixups.
To create a single check:
1. In the Proles panel of the Preight dialog box, click the Select
Single Checks buon.
2. Choose Options > Create New Preight Check.
3. On the right side of the dialog box, select a group, select a property
for the group, and then click Add. e new single check appears in
the group appropriate to its group and property.
To create a single fixup:
1. In the Proles panel of the Preight dialog box, click the Select
Single Fixups buon.
2. Choose Options > Create New Preight Fixup.
3. Name the xup and specify the criteria. e new xup appears in
the group appropriate to its category and type.
