Failed PDF/A-1b validation after conversion

Aspose.PDF Product Family
1

Hello,



We have a PDF file, which we are converting to PDF/A-1b format using Aspose.Pdf.dll of 17.4.0 version.

The result of conversion does not pass validation for compliance with PDF/A-1b in Preflight of Adobe Acrobat Pro 9.5.5.



Please find the source and converted files in attachment.



Thanks in advance.

Hello,
I am having a similar issue with some pdfs, not all. They are converted to PDF/A-1b and then are validated, both using aspose.pdf-20.10 java library and the validation fails. This happens only on Linux, on Windows the validation returns success. I have attached the source code in java and a sample pdf whose convertion fails.

We would like to share with you that the earlier logged ticket has been resolved. A PDF/A document must embed all fonts in use and when some of the fonts are absent - the conversion to PDF/A will not be successful. If the conversion was not successful then the validation will fail too. It looks like that in your Linux atmosphere, the fonts that were used in the document are absent. Usually installing basic MS fonts is enough (http://corefonts.sourceforge.net/).

Also, you could add a local font path by using the option: FontRepository.addLocalFontPath(PATH_TO_FOTNS);
Please see “aspose.log” that was created after running the program for more accurate information.

Pay attention that a first argument of the function: doc.validate(filenameAfter, PdfFormat.PDF_A_1B) it is not a PDF file (as in the program), but an XML log with resulting of validation.

If the error persists, please share the output pdf, conversion log, and validation logs.
