When creating PDF often two requirements seem to clash:
- The PDF needs to be printed (so ideally PDF/X-4)
- The PDF needs to be accessible (tagged) and to be archived (so PDF/A)
Why not create two PDF files (one /A and one /X)?
Sure, you could. It’s asking for trouble though, as you archive something that you didn’t print. And you would have to always keep two files.
Why not create a single PDF that complies to both standards?
That is ideal.
And QuarkXPress 2018 is the first graphic app for creative pro’s to create a SINGLE PDF that complies to both standards, PDF/A-2u and PDF/X-4, at the same time. So you can print them and archive them and they are accessible.
