Meaning of BLEED in English
Bleeds are when the printed inks run all the way to the edge of the paper. To accommodate the bleed, we must make the bleed area larger than the final trim size. The page is then trimmed right through the bleed area. This adds cost to your job since we have to use larger paper than the final trim size.
