Can't convert combined scanned documents to PDF/a (Acrobat Pro X and 2017)
I have multiple documents that need to combined to PDF/A. They may be any combination of the following:
-Word documents generated from templates
-PDF documents generated from Word documents
-PDF documents generated from scanned documents (in PDF/A format with OCR, both from the scanning software; these are the majority)
-PDF documents generated from fax-to-email (not in PDF/A format)
The documents might be anywhere from a few pages to several hundred pages. Many have been faxed/printed then later scanned. They contain printed text, handwriting, images, logos...some in poor quality due to multiple faxes back and forth.
I am using Acrobat Pro 2017 and had the same issue with Acrobat Pro X. I am running into frequent problems combining these documents and saving them as PDF/A. Preflight analysis indicates "font not embedded (and text rendering mode not 3)" and "fix" is unable to resolve the error.
What perplexes me is that I can start with two PDF/A documents, enable editing to combine them, then save as PDF/A and still get the error. I've seen forum posts where people discuss needing to address PDF/A compliance with the original documents rather than after combining, but shouldn't this work if that's the issue? What am I missing?
My backup plan is to print to PDF then try again, but that's not the most efficient process. I was really hoping to set up an action to plow through a bunch of folders and combine/convert the contents with minimal user input, and I'm not sure if I can do this with this approach.
If anyone can explain why this is happening or offer suggestions on how to resolve the issue, I would appreciate it. I'm at a loss. Thanks!
