Unless changed in the application preferences, PDFClerk Pro defaults to using the crop box when rendering pages, but it can be set to use any of the other boxes for rendering. When showing the original master pages each page is drawn according to the box selected from the Draw submenu of the Tools menu. When rendering an imposed layout however, PDFClerk Pro always renders the media box of each imposed sheet, but renders the imposed pages themselves onto the sheet according to the selected display box. This flexibility makes it possible to, e.g, impose an original document whose pages include finishing marks, without the finishing, which are inappropriate for the imposition, appearing on the imposed sheets. The sheets themselves can have finishing marks defined in PDFClerk Pro.
