Comprehensive Guide & Technical Breakdown
A CAD dieline is the 2D technical vector drawing that acts as the blueprint for cutting and folding a box. Standard industry line colors prevent costly manufacturing errors:
### Standard Dieline Color Coding:
- Solid Red Lines (Cut Lines): Tells the laser die-cutter where to cut completely through the paperboard.
- Solid Green or Blue Lines (Crease / Score Lines): Indicates where the die will press a blunt crease into the board for clean folding without cutting through.
- Dashed / Dotted Lines (Perforation Lines): Indicates partial cuts and ties for easy-open tear strips.
- Cyan / Gray Boundary (Bleed Line): Positioned 3mm outside the cut line; background artwork must extend fully to this boundary.
- Inner Safe Margin (Safe Zone): Located 3mm–5mm inside the cut/fold lines; all text, logos, and critical graphics must stay inside this zone.
