The PAC 2024 Checker is used by agencies and service providers who are tasked with creating accessible documents, as well as by clients who check the documents provided.
When creating accessible PDF documents, the PAC 2024 Checker is usually used towards the end of the creation process, after the almost finished document is exported as a PDF. However, it should also be used from time to time to check whether the document is constructed in the correct basic structure. As soon as the PAC issues error messages for the document, you should try to correct these errors in the creation program (e.g. Word, InDesign, etc.). This minimizes the number of error messages that ultimately have to be corrected manually. And that is basically the goal, since error messages have to be corrected manually every time the document has to be re-exported (e.g. due to changes in content). Experts can usually see at a glance which PAC 2024 error messages can be corrected directly in the creation program and which error messages have to be corrected manually at the end of the creation process.
Look now, how to use PAC 2024 to check PDF documents for accessibility.
