Using this tool

Inspect a PDF before printing

The PDF inspector shows font embedding and encoding, colour resources and ICC profiles, page boxes and document metadata. A separate artwork scan reports invoked font/colour use, placed image resolution, transparency and overprint, with visible scan limitations.

  1. Choose the PDF you want to inspect.
  2. Run Inspect PDF to process the file and display its report.
  3. Review the font, colour and page information before preparing your print file.

Inspection is read-only and does not change the original. Resources and invoked artwork are reported separately. Incomplete scans are identified; findings do not certify visible pixels or print readiness.

Processing happens temporarily on our server when you run a tool. We do not retain your documents, address lists or results. Read our Privacy.
