I am creating a map for the centerfold of a newspaper.

The working size is 20" wide by 16" tall.

The printer needs it in two 10x16" PDF pages.

Is there a way to export just one half of the image at a time or ???

I am trying to avoid anything that involves me actually touching things. For example, I could reduce the page to 10x16, slide the map so that the left side covers the page, export the page to pdf, then slide the map to the right and export again... However there is no guarantee I will get it to match perfectly.

Same goes for drawing a 10x16 box and using clip view... Too imprecise.

I need a way that will exactly divide the page in two, so if the two PDF's printed side by side don't line up perfectly, it is due to the printer's issues and not my poor page split.

Suggestions????
