Summary

For professional print results, always set Bleed (3 mm beyond the trim line), Trim (final size), and Margin (safe zone at least 3 mm inside the trim). Bleed prevents white edges from cutting misalignments, while margins keep text and key elements safe. If your software can’t set bleed, simply add 3 mm to each side of your artwork size and keep important content at least 6 mm from the edge.

When preparing files for print (e.g., business cards, flyers, brochures, notebooks, or books), it’s crucial to set Bleed, Trim, and Margin correctly to ensure professional results.

Example of creating a file and setting guide lines in Adobe Illustrator

• Bleed: Extra area (≥3 mm each side) that extends beyond the trim line, cut off after printing. Prevents white edges from slight cutting misalignments.

• Trim: The final finished size of the printed piece.

• Margin (Safe Zone): Area inside the trim where all key text and design elements should stay, at least 3 mm away from the trim line.

Examples of good and bad files regarding margins and safe areas for printing

Because sheets are often cut in stacks, minor misalignments can occur. A proper bleed ensures the design looks seamless even if trimming isn’t perfect.

The bleed area should seamlessly continue the design without any visible separation.

The area with the arrow pointing is not seamless.

Tip: If your software doesn’t support bleed settings, add 3 mm to each side of your artwork size (e.g., 90 × 55 mm → 96 × 61 mm). Keep all critical elements at least 6 mm away from the edge.
