Concept
Bleed refers to the 3mm area extending beyond the trim line of printed material. It ensures that backgrounds or images fully cover the edges, preventing unwanted white borders after trimming. The bleed line is a fundamental element in print design, and applying it correctly guarantees a clean, professional finish.

• Extend backgrounds or images beyond the bleed line.
• Keep text and key elements inside the safe zone.
• Ensure the exported PDF includes bleed settings.

Example
For an A4 final size:

• Final size: 210mm x 297mm
• With bleed: 216mm x 303mm (3mm bleed on each side)

This ensures that even with slight trimming variations, the edges remain fully covered without unwanted white borders.

Illustrator Setup

• Set bleed size in Document Setup (commonly 3mm).
• Extend design elements into the bleed area.
• Check “Use Bleed” when exporting PDF.

Photoshop Setup

• Add bleed size when creating a new document (e.g., A4 210mm x 297mm → 216mm x 303mm, with 3mm bleed on each side).
• Extend design to the edges.
• Ensure bleed is included when exporting.
• Note: Photoshop is not ideal for layout; Illustrator or InDesign is recommended for professional printing.

InDesign Setup

• Set bleed value in Document Setup (3mm).
• Extend design elements into the bleed area.
• Check “Use Document Bleed Settings” when exporting PDF.

CorelDRAW Setup

• Include bleed size when creating a new document.
• Extend design into the bleed area.
• Set bleed value (e.g., 3mm) in the export dialog.

Helpful Reminders

• Always confirm bleed requirements with your printing provider. Keep text and important elements within the safe zone.
• While multiple software options support bleed, Illustrator and InDesign are recommended for professional printing projects due to their advanced layout and print features.
