Reply To: Splitting a gradient across a spread CS5.5

If you export these pages to PDF, the individual PDF pages will each have their own half of the gradient. If there's an absolute need to split the graphic, then do that and replace the double truck graphic with the appropriate PDF on each page.

Normally, in a situation like this I simply send the PDF of the whole publication to the printer, which avoids any necessity to split a graphic that happens to cross a spread. (The same consideration applies to photographs or any graphic that runs across a spread.)
