Let us try copying and pasting its contents into a text file. Special steps, and then converted to PDF/A-1b using Acrobat Pro. Generated from LaTeX sources using pdflatex without any It will typically generate empty metadata and incorrectįor example, consider two PDF/A documents containing this paragraph That the resulting PDF/A-1b is of poor quality: if the inputĭocument did not contain metadata or Unicode mappings, then theĬonversion software will not be able to create this data out of ![]() While one can sometimes get away with this method, the problem is "plain old" PDF file from your LaTeX sources, and then convert it to I.e., documents that meet the technical requirements, but not theĪlmost any PDF document can easily be converted to PDF/A-1b, usingĪutomated software tools such as the "Convert to PDF/A-1b" option of ThisĮncourages authors to submit PDF/A documents of poor quality, Validation of PDF/A documents, skipping manual validation.

In such situations, either the document's author, or the ![]() Should remain readable for the indefinite future. This makes sense, because such documents will be archived, and Many organizations, such as universities, require certain documents, We will also beĬoncerned with Unicode mapping, which is optional, but highly Self-containedness and the presence of metadata.
