Nothing delays a label order like artwork that needs rework. The short answer: send a layered PDF/X-4 with the dieline on its own spot colour layer, 3 mm bleed, CMYK plus named Pantones, outlined fonts, 300 ppi images, a black-on-white barcode and every finish on a named layer. This tutorial covers exactly what your label printer needs, and why, so your job moves straight from approval to press.
Step 1: Start From the Dieline
The dieline is the exact cut shape of your label, supplied as a vector outline on its own layer. Always design inside the dieline your printer provides (or request one before starting). Keep the dieline as a spot colour set to overprint, and never merge it into the artwork.
Step 2: Set Bleed and Safe Zones
- Bleed: extend backgrounds and images at least 3 mm beyond the dieline on all sides so tiny cutting variations never leave white slivers.
- Safe zone: keep text, logos and barcodes at least 3 mm inside the cut edge.
- Curved containers: allow extra safe margin near vertical edges where wrap-around tension is highest.

Step 3: Get Colour Right (CMYK vs Pantone)
Design in CMYK, not RGB: screens show colours print cannot reproduce. For brand-critical colours (your logo red, a signature teal), specify a Pantone (PMS) number; presses can then match it as a dedicated ink or a calibrated simulation.
Rich black tip: for large black areas use a rich black mix (e.g. C60 M40 Y40 K100); for small body text use 100 K only, so registration stays razor sharp.
Step 4: Handle Fonts and Strokes
- Convert fonts to outlines (or embed them) before export.
- Minimum recommended text size: 4 pt positive, 5 pt reversed (white text on dark).
- Minimum stroke width: 0.25 pt positive, 0.5 pt reversed.
Step 5: Images at the Right Resolution
Placed images should be 300 ppi at final size. Upscaling a small web image will print soft. Vector artwork (logos, illustrations) scales infinitely, so prefer it wherever possible.
Step 6: Barcodes That Actually Scan
Keep barcodes black on white, at 80% magnification or larger, with quiet zones intact. Avoid printing barcodes in colour or reversing them. For GS1 sizing rules, see our barcode printing guide.
Plan ahead for 2D codes. GS1's 2D Barcodes at Retail Point-of-Sale guideline sets an initial goal for point-of-sale scanning to read the GTIN from both linear and 2D barcodes by the end of 2027, and states that 2D barcodes cannot immediately be the only barcode on pack until 2D scanning is ubiquitous. Keep your EAN or UPC in the artwork, and if your brand owner plans to add a GS1 Digital Link QR code or a GS1 DataMatrix, reserve a separate clear area with its own quiet zone for it. See our guides to QR codes on packaging and variable data printing.
Step 7: Mark Special Finishes on Separate Layers
Foil, spot UV, embossing and white-ink areas each need their own clearly named spot-colour layer (e.g. “FOIL”, “SPOT-UV”, “WHITE”). This is how premium effects like the ones in our premium label guide are communicated to press.
Step 8: Export Correctly
- Export PDF/X-4 (preferred) with bleed and dieline layers intact.
- Do not flatten transparency manually: let pre-press handle it.
- Include a view PDF or JPEG so intent is unambiguous.

FAQ
What file format should I send my label printer?
A layered PDF/X-4 exported from Illustrator or similar, with dieline and finish layers as named spot colours, fonts outlined and 3 mm bleed. Native AI files are a good accompaniment.
Why does my printed label look duller than my screen?
Screens are RGB and backlit; print is CMYK and reflective. Designing in CMYK with a calibrated proof avoids the surprise. Critical brand colours should be specified as Pantone references.
How much bleed do labels need?
3 mm is the safe industry standard for roll labels. Some very small labels can work with 2 mm, but never design with zero bleed.
Can I use Canva for label artwork?
Canva works for simple designs if you export PDF Print with bleed and convert to CMYK afterwards, but complex jobs with dielines, white ink or foil layers are better prepared in professional tools, or handed to your printer to finish.
