A dieline is the flat template of a box: an outline showing every cut, fold and glue line before the box is assembled. Printers use it to place your artwork and to cut the board. The Best Price Boxes sends a dieline with every quote, with no minimum order, and we beat any written quote for the same specs.
What a dieline shows
Lay a finished box flat and trace its outline and you get a dieline. It marks three kinds of lines. Cut lines show where the blade goes through the board. Fold or score lines show where the board creases. Bleed and safe-area guides show how far your color must run past the edge, and how far inside the edge your text must stay so it is not trimmed or lost in a fold.
Dielines are usually supplied as vector files, either PDF or AI, with the guide lines on their own layer so they do not print. Your artwork goes on top of that layer, never inside it.
Why the dieline decides the box
The dieline sets the real, usable size. Two boxes with the same outside dimensions can have different inside dimensions depending on board thickness and style, which is why we ask for the inside size and build the template around it.
| Dieline element | What it does |
|---|---|
| Cut line | The outline the die cuts through |
| Score or fold line | Where the board creases |
| Bleed | Extra color past the cut so no white edge shows |
| Safe area | Where text and logos should stay |
| Glue flap | The tab that bonds the box together |
| Minimum order | None |
How to work with one
Open the file in your design software, lock the dieline layer and build your artwork on a layer above it. Run color to the bleed line, not just the cut line. Keep text and logos inside the safe area, and remember that anything on a glue flap gets covered when the box is made. Panels on the box can sit upside down or sideways on the flat sheet, so check which panel is the front before placing a logo.
Fold your layout mentally. Print a copy at full size, cut it out, and crease it by hand. A paper mock-up catches wrong-way artwork and cramped fits in minutes, before you approve a proof. If you have no design software, tell us and we help place the artwork.
Where to get one
Every quote from us comes with a dieline sized to your product. Send inside length, width and height, plus a quantity, even one, through the quote form. Design, samples and shipping are free. A shape you have not seen before can be compared on a product page first: tuck top boxes, rigid boxes and corrugated boxes each use a different template. For a style comparison, read straight versus reverse tuck end boxes. For finishes that need their own layer, see embossing and debossing.
Questions buyers ask
What is a dieline in packaging?
A dieline is the flat template of a box showing cut lines, fold lines and glue flaps. It guides both artwork placement and the cutting die.
Which file format should a dieline be in?
Vector, usually PDF or AI. Keep the dieline on its own layer so it does not print with your artwork.
What is bleed on a dieline?
Bleed is extra color that runs past the cut line, so a small trimming shift does not leave a white edge. Extend background color to the bleed line.
Do I need to design my own dieline?
No. We send a dieline with every quote, sized to your product. You only need inside dimensions and a quantity, even one box.
