Convert to PDF/A-1a file

[Ryan_...@adobeforums.com]

Hi,

I'm using Windows Vista/Acrobat 9 Pro (v9.0.0) and I want to convert old PDF's to the PDF/A-1a format but I can't seem to figure out how. My old PDF's are different file versions and want to convert them to the PDF/A format. I don't have the original files, I only have them in the old PDF format.

I went to Advanced->Print Production->Preflight and selected the 'Verify PDF/A Compliance' then clicked on 'Analyze and Fix'. This gives me a bunch of errors stating that it is not PDF/A compliant and produces a report. From here I can't figure out how I'm supposed to go about making it PDF/A-1a compliant because it does not say anything further.

I am new to Acrobat so I have a feeling it may be just me not knowing how to fix each problem within Acrobat. I thought that when I hit the 'Analyze and Fix' button it would fix it for me or tell me it can't fix it due to reason 1, 2, 3, ...

Thanks in advance for your help,
Ryan.

Can you elaborate on the error messages you get?

[Ryan_...@adobeforums.com]

The errors that I get are:
1)Structured PDF: Structure tree root entry missing
2)Creation date mismatch between Document info and XMP metadata
3)Creator mismatch between Document Info and XMP Metadata
4)Last Modification Date mismatch between Document Info and XMP metadata
5)Producer mismatch between Document Info and XMP Metadata
6)MarkInfo missing
7)Metadata missing
8)PDF/A entry missing

Does Adobe have a list of these errors somewhere and how to fix them?

Thanks.

So the first question you need to ask yourself is "Why 1a and not 1b?" 1a has a LOT of extra requirements in the area of structure and tagging that need to be met in the final document and if your originals don't have them it is difficult/impossible to acquire them. This is where your errors #1 and 6 come from. If you went with 1b, those go away.

So now, why 2-5? those happen because somewhere between when you created those PDFs and now they have been modified by an old PDF program that didn't follow the rules :(. Not a big deal, however, Acrobat's Preflight tool can fix them when you do a "Convert to PDF/A-1b".

7 & 8 just tell you that this isn't (yet) a PDF/A-1 file - but both will be fixed up when you convert using Preflight.

See - no problems!

I am converting documents into PDF/A-1b format and I am getting the 'creation date mismatch between Document info and XMP metadata' error message. I am using Preflight to convert my pdf to PDF/A-1b (sRGB). Each time I try to convert, I get the same error message. What can I do to fix this?
