Convert PDFA to PDFX

Understanding the PDF/A and PDF/X file formats

PDF/A is an ISO-standardized version of the Portable Document Format (PDF) specialized for digital preservation of electronic documents. It ensures that the document can be reproduced exactly the same way in the future by embedding all necessary information, such as fonts and color profiles, and by prohibiting features unsuitable for long-term archiving.

PDF/X is another ISO-standardized subset of PDF, designed specifically for the graphic arts and printing industry. PDF/X files ensure reliable prepress data exchange by embedding all fonts, specifying color profiles, and restricting certain features that could cause printing errors.

Why convert PDF/A to PDF/X?

Converting from PDF/A to PDF/X is often necessary when a document originally intended for archiving needs to be prepared for professional printing. PDF/X ensures that the file meets the strict requirements of print production, such as color management and font embedding, which may differ from the requirements for archiving.

How to convert PDF/A to PDF/X

To convert a PDF/A file to PDF/X, you need a tool that supports both standards and can handle the necessary compliance checks and adjustments. The process typically involves:

• Opening the PDF/A file in a PDF editor or converter that supports PDF/X export.
• Ensuring all fonts are embedded and color profiles are correctly assigned.
• Exporting or saving the file as PDF/X, selecting the appropriate PDF/X standard (such as PDF/X-1a or PDF/X-4) based on your printing requirements.
