is there a specification to the .pdf file that Dorico creates via its file export?
Background: My publisher is asking about this. In his PDF-Viewer (Foxit Reader) he noticed some “double lines” in the page numbers which would disappear when zooming in. He asked wether it would be possible to get the .pdf files as PDF/X or PDF/X-1a (of which I have no idea what that would mean). My guess is that it might be a display issue on his side.
