Bleed and safe area for label artwork

Most artwork problems that reach a printer are not design problems. They are two measurements: bleed and safe area.

Bleed

Cutting is not perfect. A guillotine or a die can drift by a millimetre across a run, and if the artwork stops exactly at the trim line, that drift shows as a white sliver along one edge.

Bleed is extra artwork beyond the trim: typically 3 mm on every side. The background extends into it, the blade cuts inside it, and the drift lands on printed area rather than on white.

Rules:

• 3 mm bleed on all sides for labels and stickers.
• Backgrounds and images must extend into the bleed, not stop at the trim.
• Do not put text in the bleed area; it will be cut off.

Safe area

Safe area is the margin inside the trim where text and logos can live without risk. Typically 3 mm, and more on curved surfaces.

Why it matters: a label applied by hand on a curved bottle can sit a millimetre off-centre, and a die cut can drift. Text at the very edge looks like a mistake even when the print is perfect.

On small stickers (under 30 mm), a 3 mm safe area is a large share of the design — which is why small labels have less room for text than designers expect.

Curved surfaces change the geometry

A flat carton and a cylindrical bottle are not the same canvas. On a bottle:

• A rectangular label wraps around a curve, so the design’s edges are foreshortened visually.
• A label applied slightly rotated looks worse than on a flat surface, because the curve exaggerates it.
• On tapered containers, a straight label wrinkles at the top edge; a curved dieline is needed.

For a full wrap, the design must meet itself at the seam. A 2–3 mm gap is normal, and the artwork should account for it rather than leaving a random slice of the design on the back.

Dielines

For die-cut shapes, the cut path is a separate layer. Two common errors:

1. The dieline is a picture, not a vector path — the cutter cannot follow it.
2. The path is open or has stray points — the plotter follows them literally and cuts a line across the design.

Supply the path as a single closed vector shape on its own named layer.

A checklist before sending artwork

• 3 mm bleed, with background extending into it
• Text at least 3 mm inside the trim (more on curves)
• Cut path on a separate, closed vector layer
• 300 dpi for raster elements at final size
• CMYK, not RGB
• Fonts outlined or embedded
• Barcode quiet zone intact

What this means for buyers

Bleed is not optional on a full-bleed design. Without it, every copy carries a visible white edge somewhere on the run.

Small labels need more discipline, not less. The safe area eats a larger proportion of a 30 mm label, so simplify rather than shrink.

Curved containers deserve a dieline and a sample. A flat proof cannot show how a wrap sits on a tapered jar.

Ask for the artwork check before paying. A printer who reviews your file before the order is cheaper than one who reprints after it.
