Adding crop marks

[ThunderRoad]

Hi all,

I'm printing off an A5 booklet on A4 paper. What's the easiest way for me to add crop marks so I can later trim the finished product? The document itself is made on Pages. I can't see any way to do it on there, do I possibly need to convert to PDF and then do it?

Thanks

Fold the printed page in half?
