Artwork Guidelines

A practical checklist for crisp printing, clean cut lines and a proof you can approve with confidence.

300 dpi

Use the final print size when setting up artwork.

Outline your fonts

Keep your lettering looking as intended.

Check your proof

Review size, shape, border and spelling.

Your print-ready checklist

  • Set up your artwork at the final print size.
  • Use 300 dpi for raster artwork at that size.
  • Convert fonts to outlines in vector artwork.
  • Keep important text and details at least 3 mm inside the cut edge.
  • Check spelling, image quality and dimensions.
  • Do not add crop marks to your sticker artwork.

File formats & uploads

PDF, AI, EPS, PNG and JPG/JPEG are accepted artwork formats. Some product uploaders also support SVG and HEIC; follow the file types and size limit displayed beside that product’s upload field.

An original vector file gives the best result for shapes and text. Saving a low-resolution JPG as a PDF does not improve its image quality.

If your upload fails, use “Email artwork later” where offered, or email your artwork and order number to [email protected].

Cut lines & white borders

If supplying a cut line, keep it as a separate vector path with a centred 0.25 pt stroke. Make the intended cutting shape clear and keep key artwork safely inside it. Do not include crop marks.

For products offering a white border, use the border option in the calculator and check the result in the proof. Die Cut Stickers use a minimum 2.5 mm white border when that option is selected.

If you cannot supply a cut line, send a separate filled silhouette showing the shape you want, or request help with a manual proof. Artwork setup or design work may attract a separate charge; ask for a quote before proceeding. The existing artwork setup rate is $80 excluding GST per hour, with a one-hour minimum.

Fonts & fine detail

Convert text to outlines in Adobe Illustrator, CorelDRAW, Affinity or your vector design software so the lettering does not change when opened on another computer. Keep an editable copy for yourself.

Very small text and fine lines may not reproduce clearly. Check your proof at the intended sticker size and ask us if you are unsure.

Resolution & Procreate

Create your canvas at the size you intend to print and use 300 dpi. Enlarging a small image later can make it look blurry.

Example: a 100 × 100 mm design at 300 dpi needs approximately 1181 × 1181 pixels. A 10 × 8 inch design needs 3000 × 2400 pixels.

Colour on a screen can differ from print. Clear and holographic materials can also change how colours look. Use the proof to check layout and cutting details; a screen preview is not an exact colour sample.

QR codes: size, design & scan testing

We recommend QR codes be at least 10 × 10 mm (1 × 1 cm) at the final printed size. Use a clean, simple design with strong contrast and a clear, uncluttered margin around the code for easy scanning. Avoid fine details, busy backgrounds or decorative effects that make the code difficult to capture.

It is the customer’s responsibility to test every QR code at 100% of its intended print size before approving the artwork. Print a sample at actual size, without “fit to page” scaling, and check that it scans and opens the correct destination. Testing an enlarged image on a screen is not a substitute for testing at the finished size.

Supply sharp, high-resolution artwork, preferably an original vector file. Low-resolution images can blur the code’s small details. Lamination and other finishes may introduce glare or reduce clarity, making scanning more difficult, particularly when the supplied artwork is low resolution. The recommended size is not a guarantee that every code will scan; design, resolution, material, finish and scanning conditions all matter.

QR codes of any size: Customers are responsible for the design, content, destination and testing of all QR codes. Where we have printed the approved artwork correctly, Sticker Ninja is not responsible for QR scanning or destination failures caused by customer-supplied artwork, code design, resolution, contrast, scanning conditions, or expired, incorrect or unavailable third-party links and QR services. This applies to QR codes of every size; the recommended size is not a guarantee of scanning performance. This does not exclude your rights under Australian Consumer Law or our responsibility for printing errors.

Before you approve

Review spelling, orientation, size, shape, border and the cut line. If anything looks wrong, request a manual proof or contact us before approving. Artwork awaiting a manual proof is not approved for production.

If your artwork or size changes, check the new proof before production. See How it works for the ordering steps.
