So, like any bitmap, the only way to increase DPI is to shrink the size. If you import a page of a PDF into a page-sized frame, then export to PDF, you are likely to be disappointed at the loss of resolution. > >> Output DPI is set in the PDF export requestor. >> > > Oh, thank you.

That is the same as the "preview > settings" in the context menu. What does low/normal/full resolution stand > for? I don't know precisely, but this is simply the display that you see and manipulate.
