Sticker Artwork Guide: Size, Bleed, Cut Lines, CMYK & Print-Ready Files

Artwork problems cause more sticker order delays than any other single factor, because a sticker's cut line has to follow the design exactly, unlike a simple rectangular print where a small misalignment barely shows. Getting the file right the first time keeps your order on PrintOnline's stated production timeline instead of stuck in an approval loop.

CMYK

Submit artwork in CMYK colour mode, not RGB. Screens display colour using RGB (red, green, blue) light, while printing builds colour from CMYK (cyan, magenta, yellow, black) ink, and converting from RGB at the printing stage can shift your colours unpredictably, especially bright blues, greens and some oranges. Set your file to CMYK from the start in your design software rather than converting at the last step.

Resolution

Use 300 DPI (dots per inch) at the sticker's actual final print size. A design that looks sharp on screen at 72 DPI, the standard screen resolution, will print visibly blurry or pixellated, since screens and print need very different pixel densities to look equally sharp.

Vector artwork

Wherever possible, especially for logos and custom-shape stickers, supply vector artwork (AI, EPS, or PDF built from vector paths) rather than a raster image (JPG, PNG). Vector files scale to any size with perfectly crisp edges, which matters enormously for a cut line that has to track your design outline precisely; a raster file's edges are fixed to its resolution and can look jagged once the cut line follows them at a different size than the original.

Cut lines

For any custom-shape sticker, the cut line is a separate element from your visible design, usually supplied as its own vector path on a labelled layer or spot colour, telling the printer exactly where to cut. An unclear or missing cut line is one of the most common reasons a custom-shape sticker order needs a revision before production can start; if you're not sure how to set one up, PrintOnline's design support team can prepare it from your artwork.

Bleed

Bleed is the small margin of your design that extends past the intended cut line, ensuring no unprinted white edge appears if the cut shifts by a fraction of a millimetre during production, which is a normal part of any cutting process. For sticker work, keep any background colour or image that should reach the edge extended slightly beyond your cut line, rather than stopping exactly at it.

Fonts

Convert all text to outlines (also called "create outlines" or "expand" depending on your software) before submitting artwork. This locks the exact letter shapes into the file itself, so the design doesn't depend on the printer having the same font installed, which can otherwise cause text to reflow, substitute to a different font, or disappear entirely.

Minimum line thickness

Very fine lines, whether in illustration detail or in the cut line itself, don't always reproduce cleanly at small sticker sizes; a line that looks fine on a large screen can become unreadable or physically fragile once printed and cut at a few centimetres. Keep fine detail proportionate to your sticker's actual final size, and avoid single-pixel-width lines in any raster elements.

Transparent backgrounds

If you're designing for a transparent or clear sticker material, keep in mind that any area without ink will show the surface underneath, not white. Design specifically for this: elements meant to look solid need full opaque colour behind them, while elements meant to blend into the background surface should be left genuinely unprinted rather than filled with white.

Small text

Avoid very small body text on stickers below roughly 1cm in overall size, since even correctly prepared small text can become difficult to read once physically printed at that scale, regardless of resolution. Reserve small-format stickers for simple logos, icons or short wordmarks rather than paragraph-length text.

Logo preparation

For a custom-shape logo sticker (see PrintOnline's Print and Cut Different Shapes Vinyl product), supply your logo as a clean vector file with the cut line set to follow the logo's outer silhouette, simplified slightly if the original has very fine or overlapping fine details that would be difficult to cut cleanly at your intended sticker size.

Kiss-cut artwork

For kiss-cut stickers on a shared sheet or roll, make sure adequate spacing is left between individual sticker shapes on the layout, so the kiss-cut line for one sticker doesn't run too close to its neighbour, which can weaken the backing sheet or make peeling individual stickers awkward.

Die-cut artwork

For die-cut work, where the piece is fully separated during cutting, ensure your cut line doesn't include any unsupported thin protrusions (a very narrow point or tail extending from the main shape), since a fully separated die-cut piece has no backing sheet holding a fragile thin section in place the way a kiss-cut sticker's liner does.

If you're not sure your file is ready

PrintOnline offers design support for customers who need help preparing artwork rather than submitting print-ready files themselves; check the specific product page for current design support options, or reach out via WhatsApp on +971 52 383 1019 before placing your order if you're unsure whether your file meets these requirements.
