- Trapped
- Not Trapped
- Unknown
To change the trap flag setting select the Fix check box. For example, if you select Trap flag is not set to Trapped and PDF Preflight detects that the flag isn't set to trapped in the PDF file, PDF Preflight changes it to trapped when you select the Fix check box.

Format
PDF version is
Determines whether the PDF file is Not Equal to or Less Than PDF version 1.3, 1.4, or 1.5. Adobe Acrobat 4.0 and later fully supports PDF version 1.3.
Besides Options, select the PDF version.
PDF Preflight checks for PDF 1.4 or PDF 1.5 objects in the PDF file. If the file includes PDF 1.4 or 1.5 objects, most software cannot process the file correctly without flattening and converting it to PDF 1.3. Note that a PDF file may be created by Acrobat Distiller 5.0 and later and still be compatible with PDF 1.3.
PDF uses more advanced features than
Determines whether the PDF file uses more advanced features than PDF version 1.3 or 1.4.
PDF Preflight checks for PDF 1.4 or PDF 1.5 objects in the PDF file. If the file includes PDF 1.4 or 1.5 objects, most software cannot process the file correctly without flattening and converting it to PDF 1.3. A PDF file may be created by Adobe Acrobat Distiller 5.0 and later and still be compatible with PDF 1.3.
Nonoptimal compression
Identifies the methods of compression for the PDF file. PDF Preflight uses ZIP and LZW compression for color images that are not optimally compressed and CCITT compression for monochrome images that are not optimally compressed.
To use ZIP compression select the Fix check box.
Document is ASCII encoded
Determines whether the PDF file uses ASCII or binary encoding. ASCII encoding works on all platforms and operating systems. Binary encoding provides smaller files and is acceptable in most situations.
To remove the ASCII encoding select the Fix check box.
Document is damaged
Determines whether the PDF file has missing objects, such as graphics.
PDF2Go Files
Detects files from PDF2Go software. PDF Preflight detects whether the PDF file is a Brisque or PDF2Go file or a PDF version of the Brisque Export PostScript file. PDF2Go files include only CEPS (CT/LW) data and should be protected from data manipulation, such as overprint and trapping.
Document contains Layers
PDF Preflight detects whether the PDF file has layers.
Document structure is compressed
PDF Preflight detects whether the PDF file metadata structure is compressed.
Security
Encryption
Determines whether the PDF file uses any encryption. Third-party software, such as Acrobat, can use encryption to restrict access to a PDF file. You can also set a password that restricts functions (for example, printing or selecting text) and restricts other people from changing the security options that you selected.
Printing
Determines whether the PDF file permits printing.
Content editing
Determines whether the PDF file permits content changes.
Annotation editing and form authoring
Determines whether the PDF file permits changes to annotations, including links, bookmarks, attachments, and comments in the file. This also detects whether the PDF file allows the creation of forms. A PDF form can collect data from a user and then send the data via e-mail.
Metadata
Document contains form fields
Detects whether the PDF file contains interactive form fields to be filled in by the user. The data from these fields can be exported or imported into other programs.
Document contains article threads
Detects whether the PDF file contains article threads, which link together items of content within the document that are logically connected but not physically sequential. For example, magazines and newspapers arrange text that may flow from column to column and sometimes across multiple pages. In Acrobat, you use the Article tool to create a series of linked rectangles that connect the various sections of an article.
Document contains JavaScript
Detects whether the PDF file contains JavaScript, which can be added to a form field, link, bookmark, document, or page action.
Document contains thumbnails
Detects whether the PDF file contains thumbnails. Thumbnails are miniature previews of the pages in a document. In Acrobat, you can use page thumbnails to jump quickly to a selected page and to adjust the view of the pages.
Document contains bookmarks
Detects whether the PDF file contains bookmarks. A bookmark is a type of link that appears on the Bookmarks tab in the navigation pane. Each bookmark goes to a different view or location in the document. You can use electronic bookmarks as you would with paper documents—to mark a place in a document to which you want to return. You can also use a bookmark to direct the reader's attention to where you want it.
Document does not conform to tagged PDF conventions
Detects whether or not the PDF file conforms to tagged PDF conventions (by determining whether or not the file contains the key Marked set to the value true in a MarkInfo dictionary).
A PDF conforming to tagged PDF conventions allows applications to easily extract and reuse content from a PDF document. The conventions are described in the PDF Specification.
Document contains actions
Detects whether the PDF file contains actions. In Acrobat, an action is an event that you can assign to a link, bookmark, page, and form field. It can include displaying a specified destination in a document, opening a file, submitting a form, and playing a sound or movie.
Document contains unused destinations
Detects whether the PDF file contains unused destinations. A destination is a particular view of a document, including the page of the document to be displayed and the zoom to use when displaying the page. Destinations may be associated with outline items, annotations, or actions.
