Errors in the converted PDF/A file.

Question

I am facing an issue in the converted PDF/A file.

I have combined 3 PDF documents (File A, File B, File C) into a single PDF document and want to convert it into a PDF/A document. But after this conversion, File B in the PDF/A document has issues - same text appears twice in different positions (see the attached snapshot of one of the pages). The issue is only with File B in the converted combined document. When I converted individual File B pdf into PDF/A file, there was no issue.

I have tried recombining the individual PDFs and then converting. However, the issue persists.

I will appreciate your assistance. Thank you.

Hello Souvik,

I also noticed, that only the pages with images faced this issue.

Is it related?

I will send you the concerned file via message, as you said.

Thank you.

Hi @namrata_6400,

Understandable. You might want to try another step.

That would be to convert the original PDF file (publication) to a Word file.

Once done, you can recreate a PDF file from the Word document. When creating, in the preferences of the PDF maker, go to Advanced settings-> Fonts-> check the options "Embed all fonts" and "Embed all OpenType fonts."

Try combining the newly created PDF with your thesis and let me know if that works.

Hi @namrata_6400,

Hope you are doing well. Sorry for the trouble.

From the screenshot, a few possibilities:

(1) The program that generated the PDF file did not embed the fonts referenced by the text in the PDF file. As such, especially if fonts other than Helvetica, Times, Arial, Courier, etc. are used, the substitution fonts may not be able to adequately emulate the original font.

(2) In conjunction with (1) above, if the PDF creation software didn't properly generate font information for the non-embedded fonts, the widths and spacing used when substitution.

Again, if possible, would you mind sharing the files with me for testing in-house and get back to you?

You can send the file as a private message. To do so, click on my profile name followed by the blue "Send Message" button.
