Your sticker's edge is an instruction, not a drawing.
Kiss cut sticker artwork is not simply a design placed inside a shape. A print-ready file has to tell production two separate things: what should be printed, and where the sticker should be cut. Bleed, cut line, safe zone and spacing are how it says both.
On screen, a sticker appears to end exactly where the artwork ends. In production, two processes decide the edge. The press lays down the ink, and then a blade follows a vector path through the face material and stops at the backing. The two are registered closely, but never to the micron, so every sheet carries a small tolerance. Good artwork is simply artwork built to absorb that tolerance.
Get it wrong and the faults are small but obvious: a hairline of white along one side, a border thicker at the top than at the bottom, or a phone number trimmed by a millimetre.
Before you upload: the short version
- Bleed: extend the background beyond the finished cut.
- Cut line: a separate vector path that defines the finished edge.
- Safe zone: keep important content away from the cut.
- Spacing: leave room between neighbouring cut paths for bleed and tolerance.
- File: a PDF prepared to the printer's specification for your product.
How Kiss Cutting Works, and Why It Shapes Your Artwork
A kiss cut goes through the printed face layer and its adhesive but leaves the backing sheet intact, so each sticker peels away while the sheet stays whole. A die cut goes through the backing as well, a choice covered in its own article in this series. Because the cut is a separate instruction from the print, most artwork problems begin when the two get mixed up: the cut treated as part of the design, or the design assumed to stop exactly where the cut falls.
