PDF Creation Engines

PDFs can be generated through various software tools, each with its own way of structuring content internally. Understanding how a PDF was created helps diagnose differences in how files are rendered, analyzed, or proofed.

Common PDF creation sources include:

  • Adobe tools: InDesign, Illustrator, Photoshop
  • Office tools: Microsoft Word (Export to PDF)
  • Specialized engines: Ghostscript, Cairo, LaTeX
  • Online converters: Web-based PDF generators and converters

These variations can affect how proofing software interprets the file, such as:

  • Layering of text, vector, and image elements
  • Whether fonts are embedded or substituted
  • Image compression and color profile handling
  • Presence and accuracy of metadata.

Why it matters for proofing?

The internal structure and creation method of a PDF can influence color accuracy, text extraction, and automated comparison results. While our proofing system supports most PDF types, knowing the source tool can help identify and resolve display or validation issues more efficiently.
