Checklist for Print-Ready PDF/X Files

  • Embed Fonts: All fonts used in the document must be embedded in the PDF/X file. This includes not only text within the main body of your document but also all headlines, subtitles, and captions. For example, if Helvetica and Times New Roman are used, they must be embedded within the PDF/X.
  • Use High-Resolution Images: For clear, sharp printing, images should carry a minimum resolution of 300 DPI. For example, a 2″x3″ picture requires a resolution of 600×900 pixels minimum.
  • Include Bleed: If your design extends to the edge of the page, include a bleed margin. Usually, 1/8th of an inch (0.125″) is a standard bleed for printing.
  • Convert Colors to CMYK: Although PDF/X supports both RGB and CMYK, it’s always best to convert colors to CMYK for printing. CMYK delivers more accurate color reproduction.
  • Use Proper ICC Profiles: Select the correct ICC color profile based on the printing conditions. For instance, if coated paper is your output medium, an ICC profile like “Coated FOGRA39” is appropriate.
  • Incorrect Color Spaces: Ensure RGB images are converted to CMYK, otherwise, color discrepancies could occur during printing. For instance, a bright red color in RGB may appear rather dull when printed in CMYK.
  • Forgot to Embed Fonts: If fonts aren’t embedded, and your printer doesn’t have those fonts installed, unexpected changes in the typeface might occur.
  • Improper Bleed Settings: Failing to include enough bleed could result in white edges in the final print.
  • Incorrect File Extension: Remember, it’s important to save your document as a PDF/X file. For example, files saved in PDF format instead of PDF/X might not preserve all the characteristics planned for the print job.
