A4 (Single Page Numbering) To A3 (2 Page #'s per Page).
I'm tyring to make an A3 folder which I am going to bind. I am importing lots of single page A4 pdfs in CS6, so the majority of the document I have an A4 master page, with page numbering, which I then export as a pdf & then use pdf readers to print double paged at A3 size; and it works well.
However at certain points in the document I need to have A3 pages. As there are 2 pages in an A3 page I need to reflect this in the numbering. Anyone know how to do this?
