5.3 Properties of PDF documents
Categories of properties
The Enfocus Preflight Profile Editor gives you access to and control over, a large number of
properties in PDF documents. These properties have been subdivided into a number of categories
and are represented as such in the Enfocus Preflight Profile Editor.
A preflight check verifies and fixes these properties of a PDF document. Categories of these
properties are, for example:
• PDF Standards
• Document
• Page
• Color
• Rendering
• Transparency
• Fonts
• Text
• Line art
• Images
• Layers
• Annotations
• Other Objects
PDF Standards
Using the PDF Standards property, you can perform the following checks:
• PDF/X Compliance: Checks if the document conforms to the PDF/X specification of your choice.
As this is a global check, it resolves need for any other PDF/X checks in all the categories of
the Preflight Profile Editor. Therefore, other checks in the PDF/X category are disabled when
you enable this check.
• PDF/A Compliance: Checks if the document conforms to the PDF/A specification of your choice.
As this is a global check, it resolves need for any other PDF/A checks in all the categories of
the Preflight Profile Editor. Therefore, other checks in the PDF/A category are disabled when
you enable this check.
• Embedded PostScript fragments: This check allows you to find all fragments of the embedded
PostScript in a PDF document. Embedded PostScript fragments may not show up in the screen
preview but they change the appearance of the printed document.
• Trapnet annotation: This verifies that the trapnet information contained in the document
conforms to the PDF/X standard.
• Version Key: Checks whether a PDF/X version key in present in the PDF document.
• Pre-separated pages: Checks whether the PDF document contains pre-separated pages.
• Unknown objects: Checks whether the page contains objects which are unknown to Acrobat 5.
• Annotation in printable area: Checks whether the page contains annotations (except for trapnet
annotations) inside the printable area. The printable area is defined by the bleed box (if it present)
or by the trim box.
