I'm looking around for information on page bleeds. I've checked out Brad Anderson's paper on bleed tabs on frameusers.com and have hit the archives here via search, but I'm not finding what I need. 

Situation: 

The books I'm working with use a custom print size of 8"x9.5" (which may be changing due to printing costs). At any rate, the way the documents were set up, the actual page dimensions are 8.5x10, and the printer actually cuts the pages to 8x9.5 to get the bleed. I'm thinking this is a bit rediculous, and adds cost and overhead to the publishing process. I'm looking for a way to create page bleeds without having to use this workflow. 

My question: 

Is there a way to set a non-print "border" around a page? I know I can print with registration marks, but what I am looking for is a means to use an anchored frame or graphic element, position it so it runs off the printable page region, so the bleed happens without the need for post-printing cutting. 

If anyone has any ideas, I'd love to hear them! In the meantime, I'll keep searching... 

Thanks! 

Bill
