From Check List to PDF Options

More than a decade ago Chuck Weger coined the term “preflight” to define the verification process of digital files prior to printing. Since then, this process or “check list” has materialized into integrated PDF options, plug-ins, and standalone products.

One such standalone product is the Amyuni PDF Analyzer. Its purpose: to verify the internal validity and conformance of PDF documents.

Automated Batch Processing

Unlike integrated options and plug-ins, PDF Analyzer can be installed on a server to perform the preflight of large numbers of documents as an automated batch process (Figure 1) without user interaction.

PDF Analyzer validates the structure of PDF documents with customizable VB.NET rule sets (Figure 2) to ensure that the structure of documents comply with industry or custom specifications.

Customized VB .NET rules can be created, saved, and reloaded to verify that:

• PDF document object instructions, syntax, and hierarchies do not contain errors.
• Fonts and corresponding font information such as TrueType tables are properly embedded.
• Embedded graphics and images are properly compressed for specific application processing.
• PDF/A documents contain embedded fonts, XMP metadata, and device-independent colors, etc.
• PDF/A documents do not contain encryption, JavaScript, embedded files, etc.

In addition to document analysis, you can also use PDF Analyzer to compare documents, verify sensitive metadata, and extract confidential information. Its design and functions stem from years of “on the field” application deployment experiences.
