Glossary:
In graphic arts, bleed refers to the extra area that extends beyond the edge of the document. This ensures that no white margins remain after the final trimming process.
This is the inner zone where no essential text or images should be placed, as the cutting process may shift slightly inward.
In the next picture shows the bleed using red color, and the safety margin in gray:
