Bleed and crop marks are fundamental to professional print production. Understanding these concepts is essential for anyone designing materials for commercial printing.
Bleed refers to the area that extends beyond the finished trim edge of a printed piece. Typical bleed is 3mm on each side. When a design element (a background color, photo, or graphic) goes to the edge of the page, bleed ensures that after trimming, there's no unsightly white edge. Without bleed, even the most precise cutting will leave a thin white line where the paper shows through.
