PDFA-OUTPUTINTENT-MISSING
auto
The output colour profile is missing
A PDF/A-3 must declare an OutputIntent with an ICC profile — in practice sRGB for an invoice.
This defect is fixed automatically. Test your invoice to find out whether it is affected, then apply the correction with the Pipeline Pro plan.
Why this error happens
The most classic PDF/A omission. It has no visible consequence on screen, which is why it crosses a vendor's entire internal test chain unseen, until the first rejection.
How to fix it
The profile is added to the envelope. The correction changes neither the rendering of the document nor its business content.
