To enable bleed margins and cut marks around four separate printable areas to be cut out from a printed sheet, either:
1. Set the document page size to be the same as the paper size and place copies of your 4 separate smaller sub-pages manually on the page with space between to allow for colour bleeding and add manually drawn cut marks. Then just print as normal.

Will I need to drag a box inside of my box and do my work within the inner box to give myself room around the borders? Or will just setting the bleed be buffer enough? When I set the borders within one box, wouldn't that be as simple as dragging a box?
