respectfully "Full Bleed" is a red herring....
In all my years plotting from autocad starting in 1984 no printer I have ever needed to configure for
was ever capable of "FULL BLEED" , nor has any place I worked for set their title blocks up to place a dark black line at the extreme edge of the paper.
I would go so far as to say that EVERY plot I have ever done has ha a margin.
