RemarksThe crop box defines the region to which the contents of the page are to be
clipped (cropped) when displayed or printed. Unlike the other boxes, the crop
box has no defined meaning in terms of physical page geometry or intended
use; it merely imposes clipping on the page contents. However, in the absence
of additional information (such as imposition instructions specified in a JDF or
PJTF job ticket), the crop box determines how the page’s contents are to be positioned
on the output medium. The default value is the page’s media box.
