Unfortunately, things can go wrong with a PDF file, even with the best intentions.

Here are the top 10 features of problematic PDFs:


  • Placed image resolution too low
  • Fonts not embedded
  • Wrong colour space assigned
  • Incorrect trim or bleed information
  • Inconsistency with native file (hairlines, gradients)
  • Spot colour misnamed or converted to process
  • Too much compression (artifacts, quality loss)
  • Incorrect page size information
  • Transparent object issues
  • Incorrect or missing ICC profile
