Hi Cedric,
Sorry for the inconvenience and delay. Obviously our attempts to resolve this so far have not been successful.
The sample files you provided previously seem somewhat complex but I don't know what makes them unique. The smallest one for example creates a huge spool if printed and takes a considerable amount of time to save as a flattened PDF.
Do you have numerous PDF's that are problematic or are we still dealing with two of them?
Best regards,
Bruce
