I think you may be confused about the die line and the placement of the printer's marks.
The die line is not printed. It is provided as a non-printing guide to the area to be preserved after cutting. The die line is used by the die-cutter in the design of the cutting die.
The die line is a non-printing layer.
Printer's marks are always inside the printing area. That's why they are called printer's marks. They provide standard artwork to be interpreted by the press operator. Do not generate your own as they are an industry standard and the artwork is tightly controlled.
I think what you meant to say is that the printer's marks are always outside the artboard/canvas area. It is the same as cut or fold marks which are outside the display area in the flat.
Printers marks are often printed around the edge of the press sheet to be unobtrusive but comprehensive enough to be used for quality assurance and colour fidelity.
