What is Bleed?

Why professional printers often ask for bleed.

Bleed is extra artwork that extends beyond the final trim size. It prevents unwanted white edges after cutting.

Why Bleed Exists

Printed sheets are usually trimmed after printing. Even modern cutting equipment has small tolerances.

If artwork stops exactly at the trim edge, a tiny cutting variation can leave a visible white line.

Bleed solves this by extending the artwork beyond the final size.

Example

Imagine an A4 poster with a blue background.

Without bleed:

• Artwork ends exactly at the trim line.
• A small cutting shift may leave a white border.

With bleed:

• The blue background extends outside the trim line.
• The printer cuts through the extra area.
• The final poster reaches the edge cleanly.

Common Bleed Sizes

• 3 mm bleed – Most common commercial print standard.
• 5 mm bleed – Often used for larger formats and premium production.
• No bleed – Suitable when the design already has white margins.

How Convert2Print Uses Bleed

When using Illustration mode with CMYK production output, Convert2Print can generate:

• PDF/X-4 without bleed
• PDF/X-4 with 3 mm bleed and crop marks
• PDF/X-4 with 5 mm bleed and crop marks

This allows you to deliver exactly the version your printer requests.

When You Need Bleed

• Posters with full background colors
• Flyers
• Brochures
• Business cards
• Book covers
• Packaging artwork

When You Usually Do Not Need Bleed

• Documents with large white margins
• Office documents
• Internal PDFs
• Digital-only files

What Are Crop Marks?

Crop marks are small lines placed outside the artwork. They show the printer exactly where the final trim should occur.

Crop marks are outside the finished artwork and are removed during cutting.

Recommended Workflow

• If your design reaches the edge of the page → use bleed.
• If your printer requests bleed → use the requested size.
• If you are unsure → choose the 3 mm bleed version.
