What is a dieline, and why does it matter?
A dieline is the technical drawing that shows the manufacturable form of a box or die-cut label: the plan underlying the design. Every box you see on the shelf first exists thanks to a correctly drawn dieline.
What does a dieline show?
- Cut line — the outer boundary of the packaging
- Crease — the folding lines
- Perforation — tearable sections
- Bleed and safe area — the areas where printing extends past the cut and where text must stay clear
Why is it so critical?
Printing and cutting are two separate jobs that meet on different machines; the thing that aligns them is the dieline. If the line is wrong, text gets cut into, cracking occurs at the folds, locking sections don't hold — and often the die is remade and the cost repeats.
The mistakes we see most often
- Not leaving a bleed (a white line remains at the edge)
- Placing text right against the cut line
- Mistaking a crease line for a cut
- Setting the box size without measuring the product going inside
- Trying to "fit" a new design into an old die
How should you deliver your file?
Vector format (AI/PDF), the dieline on a separate layer and in a separate color, dimensions in mm, fonts converted to outlines. If your file is ready, we do the pre-production check; if you don't have a dieline, we draw one for you based on your product dimensions.
Let's clarify this decision together.
