Please advise whether these are known non-conformities with Aspose or something that can be fixed via configuration.
Many thanks,

@nedsmith

Would you kindly share a sample PDF with us so that we can test the scenario in our environment and address it accordingly.

Hi @asad.ali ,
Here is the template we are using to generate the PDF documents:
DP3.zip (38.7 KB)

Here are the documents showing the non-conformities.

Demo doc BEST.pdf (38.5 KB)
Demo docPDF-X.pdf (37.5 KB)
Demo docPDFX-1A.pdf (37.5 KB)

Here is a scan of the printed version of one of the documents (UAVD5R01.pdf) which shows the impact of the issue:
UAVD5R01.pdf (187.6 KB)
The impact is described like this:

The print out of the PDF had issues with rendering in the blue and grey right hand sidebar. The colouration around the wording had changed so it was a different shade of blue and grey from the rest of the sidebar. This had also impacted the logo at the top of the sidebar

In case it is useful, the issues with the documents can be fixed manually by following these steps:
Use Adobe Acrobat Pro:

  • -Open the file
  • -Go to “Print Production” then “Preflight”
  • -Under “PDF/X” select “Convert to PDF/X-1a (Coated FOGRA39)”
  • -Select “Analyze and fix”
  • -It’ll then prompt you to save the file which will be X-1a
    The option looks like this:
    coated fogra39.jpg (18.1 KB)

And the resulting fixed documents are here:
Demo doc BEST Fixed.pdf (517.0 KB)
Demo docPDF-X Fixed.pdf (516.1 KB)
Demo docPDFX-1A_report Fixed.pdf (517.6 KB)
We’d be interested to know if there is the option in Aspose to generate PDFs with this Coated FOGRA39 option, as this may help us resolve the issue.

Please let us know if this information is sufficent to allow you to investigate the problem.
Many thanks,
Ned
