Bleedbox
The BleedBox is one of the five PDF boxes. It describes the part of the PDF, including the content and the bleeding. In printing a bleed of 1 to 3 mm is usually required. A PDF file with an A4 page for printing so usually has a Trimbox of 210×297 mm, the trimmed page format. The BleedBox has with 3mm bleed around the page the size of 216x303mm.
Trimbox
The Trimbox is the final format of a PDF file without bleed. For an A4, the Trimbox of the PDF is therefore 210x297mm, while the Bleedbox would be 216x303mm with 3mm bleed all around.
