I have a normal template, nothing strange, with a PDF set as the background image of the Print Section. Proofs ok through Connect “Proof Print” but when output via Workflow the background is replaced with a red X.
The name of the PDF background image was quite long. On a whim, I renamed the PDF, imported it, set the Print Section to use the same, but shorter named, PDF, and the issue resolved.
Is there a limitation on the size of the path or filename for internal background images?
