Like Kalle before me, I do not know of any jargon or term to describe this…
Further, I have recently started using InDesign (ID) with any kind of depth, so I can just start to be called a beginner. 🙂
My solution would be to keep everything inside ID:
* I would make two single page ID files, one the English and one the Spanish.
* I would then make a third ID file that has two pages of the appropriate size.
* With the third file open and the other two closed, I would use File Explorer to drag one of the closed files to page 1 and the other to page 2. NOTE: File > Place… works, too, but I am lazy.
* Finally, I would rotate page 2 180 degrees. (Full-on American here – I’d have the English on page 1 and the Spanish upside down on page 2 since I can’t read it anyway.)
I see a couple of benefits to this method:
1) Faster workflow. I generally find it faster to work in one program if I know how to use it sufficiently.
2) Editing the individual English and Spanish files reflects in the combined file when you open it and update links when ID asks you.
3) One single output step to PDF from ID rather than combining in Acrobat.
Final thoughts: I automatically started to think about the publication being sent to an outside printer – that is, after all, how most people use ID. However, I print over half my work in-house. If I were going to print it myself, I would NOT rotate the Spanish page and instead tell my printer to duplex the print by “flip paper on short edge”. This would also work from any program, btw.
Hope my ideas helped.
