When I add a Watermark image to a PDF/A-2b formatted file and then check for validation (using the Online PDF/A Validator from Solid Documents) I receive several Fatal errors:
<problem severity="fatalError" objectID="70" clause="6.4" standard="pdfa" page="1">The key 'SMask' is prohibited for PDF object 'Image'. Try to use another part of PDF/A standard (e.g. PDF/A-2)</problem>
Am I allowed to add a watermark to a PDF/A-2 document after it has been created and then re-save it using the QP.SaveToFile function?

It seems this might be a problem with the latest version of PDFCreator (v1.7.1). Even though it states the format is PDF/A-2b it seems to be encoded as PDF/A-1b. However transparency (for watermarks) is only supported in the newer PDF/A-2b format - I have asked them is this a typo in their menu selections or have they got the encoding wrong.

QuickPDF can add a watermark to a PDF, although it's not as simple as having a function called "Add WaterMark" with options for transparency etc.. (perhaps this will be added into future versions of QuickPDF I'm just hoping the developers of PDFCreator will bring out a new version with this problem fixed.
