Master spreads to singles
Hi,
For a few years now, we've sent our files to the printer and they've adjusted them based on their needs. However, they now want us to do this formatting on our end. I've inherited a bunch of InDesign files with presets and masters applied to pages. The problem is concerning the inside bleed. On the individual pages of the file, this isn't a problem, however, the masters applied to those pages are formatted to be spreads rather than one-up pages. In order to extend the headers to cover the internal bleed, it would most likely be best to have single page masters, right? Otherwise it's pretty impossible to cover the inside without dragging the content of the other page in the spread along with.
Is there a way to do this without having to remake each master individually? Do I need to duplicate each spread then and just delete every other side?
I'm running InDesign CS5, if that matters.
Thanks.
