Form field tab order must match the flow of the document: left to right, then top to bottom, with the exception of columns where it makes more sense to go from the top to the bottom of the leftmost column, then return to the top of the next column to the right.

PAC2[edit]

PAC2 is an utility that checks accessibility against the PDF/UA standard, which is stricter than the standard used by the Adobe Acrobat XI accessibility checker.

Download PAC2 here or here.

It's not a normal Windows installer. Instead it unzips a folder containing an .exe and .dlls. The program can be run from that directory.

PAC2 errors and their fixes[edit]

Add errors with fixes here as they are encountered.

PDF/UA identifier missing[edit]
  • Create a file containing the required metadata. (\\diskstation\development\gsg\compliance\pdfuaid.xmp or [1])
  • Append the metadata to the file with File > Properties > Description tab > Additional Metadata... > Advanced > Append
Font not embedded[edit]

Encountered this in a PDF document containing Chinese characters. Space characters seemed to cause this error.

Hard to track down because PAC2 only shows one instance of the missing font at a time, which requires editing & saving the PDF, re-running the check in PAC2 only to find the next instance of a space character.
