MediaBox, CropBox, TrimBox and BleedBox
MediaBox is the full sheet. CropBox is the area viewers display. TrimBox is the final size after cutting, and BleedBox is the area including artwork that runs past the cut. Print shops usually need TrimBox and BleedBox set correctly; office documents rarely have them.
