Printing Design Guide

Design guide

Printed labels and signs use UV-cured digital inks on vinyl, polycarbonate, aluminium composite and other substrates. Full-colour artwork, logos and compliance layouts are all achievable — provided files meet resolution, colour and bleed requirements. Use this guide to prepare print-ready artwork for Australian industrial and safety applications.

Overview

Digital UV printing applies CMYK (and sometimes white or spot) ink directly to the label or sign surface. Unlike engraving, printing supports full-colour graphics, photographic elements, gradients and complex compliance layouts — ideal for safety signs, branding, directional signage and warning labels.

Plastic Tags produces printed safety signs, compliance labels, fleet graphics and custom signage for Australian commercial, industrial and renewable energy projects.

Print vs engrave

Printing suits complex graphics and colour-critical safety signage. Engraving suits maximum durability where artwork is primarily text and symbols. Compare both processes in our engraved vs printed labels guide.

Artwork specifications

Supply print-ready files at the finished sign or label size. These specifications apply to most digital UV print orders:

ItemRecommendation
Preferred formatPDF/X-1a or PDF with embedded fonts; also AI, EPS, PSD
Colour modeCMYK (convert from RGB before export)
Artwork scale1:1 at final dimensions (mm)
FontsEmbed or convert to outlines
Spot coloursSpecify Pantone references where colour matching is critical
Compliance signsFollow AS 1319 layout, colours and pictogram requirements

For safety and warning signs, use standard pictograms and colour fields as defined in AS 1319 and relevant industry standards. Do not resize or recolour standard symbols without checking compliance requirements.

Resolution and detail

Vector artwork is preferred for logos, text and line work — it scales cleanly at any size. Raster elements (photos, shaded graphics) must meet minimum resolution at final output size.

ElementMinimum resolutionNotes
Logos and line artVectorEmbed or outline; avoid low-res PNG upscaling
Photographs / shaded graphics150 DPI at final size300 DPI preferred for close-viewing signs
Small text (under 8 pt)Vector onlyRaster text below 6 pt may appear soft
Barcodes and QR codesVector or 300 DPI minimumTest scan before bulk print

Minimum text sizes (guideline)

  • Safety sign primary text: 25 mm cap height (AS 1319 viewing distance rules apply)
  • Secondary / instructional text: 15 mm minimum on standard signs
  • Small compliance labels: 2 mm minimum for legibility at arm’s length
  • When in doubt, increase text size rather than reducing viewing distance assumptions

Colour and ink

Digital UV printers use CMYK process colour. Screen colours (RGB) will shift when converted — always proof critical brand and safety colours in CMYK or Pantone before final production.

Colour tips

  • Convert RGB artwork to CMYK before submitting files
  • Specify Pantone coated references for brand-critical colours
  • Rich black for large areas: C40 M30 Y30 K100 (avoid registration issues on thin text)
  • White ink available on some substrates — confirm with us for dark or transparent materials
  • Safety sign colours must match AS 1319 specifications (red, yellow, blue, green fields)

Printed colours may appear slightly different on gloss vs matte laminates and on metallic substrates. Request a physical sample for colour-critical projects.

Bleed, trim and safe area

Labels and signs are printed oversize then trimmed to final dimensions. Artwork that extends to the edge needs bleed to avoid white borders after cutting.

ZoneOffset from trimPurpose
Bleed3 mm beyond trim on all sidesBackground colour/image extends past cut line
Trim lineFinal label/sign edgeWhere the product is cut
Safe area3 mm inside trimKeep text and logos inside this zone

Signs with rounded corners or custom shapes need vector cut paths supplied separately or confirmed in our template. For standard rectangular safety signs, our tooling applies standard corner radii unless otherwise specified.

Mounting holes and fixing

Keep text and critical graphics outside hole centres and edge fixing zones. See our installation guide for fixing methods and surface preparation.

Substrates and lamination

Substrate choice affects ink adhesion, outdoor lifespan and appearance. Lamination protects printed surfaces from UV, abrasion and chemicals.

SubstrateTypical usePrint notes
Self-adhesive vinylCompliance labels, decals, fleet graphicsChoose polymeric vinyl for outdoor; calendared for short-term indoor
PolycarbonateIndustrial control labels, overlaysExcellent impact resistance; laminate for chemical exposure
Aluminium composite (ACM)Outdoor signs, site boardsRigid; UV print with over-laminate for extended life
Reflective vinylRoad, mining and fleet signageSee our reflective vinyl guide
Magnetic sheetTemporary vehicle and site signageFlat artwork; avoid heavy ink coverage on edges

Outdoor signs and labels should include a UV-stable over-laminate unless the substrate is rated for direct UV exposure. Lamination adds 2–5 years of outdoor life depending on exposure and material grade.

UV and outdoor printing considerations

UV-cured digital inks bond to the substrate surface and cure instantly under UV light. For Australian outdoor conditions — high UV, heat, rain and dust — material and laminate selection matter as much as artwork quality.

  • Specify outdoor-rated vinyl or rigid substrate for external installations
  • Add anti-UV over-laminate for signs exposed to direct sunlight
  • Use mechanical fixing (screws, rivets) for large outdoor signs where possible
  • Avoid placing dark printed panels in extreme heat without ventilation gaps
  • Allow adhesive cure time before exposing new labels to weather

For long-term outdoor durability comparisons, see our guide to Material Information.

Pre-production checklist

Before you submit artwork

  • File is CMYK at 1:1 scale with 3 mm bleed on all edges
  • All fonts embedded or converted to outlines
  • Raster images at 150–300 DPI at final output size
  • Text and logos inside the 3 mm safe area
  • Safety sign colours and pictograms checked against AS 1319
  • Substrate and laminate selected for the installation environment
  • Mounting method and hole positions confirmed
  • Physical proof or PDF proof reviewed and approved

Printing design FAQs

Can I supply RGB files?

You can, but colours will be converted to CMYK for printing and may shift noticeably — especially bright greens, oranges and blues. Convert and proof in CMYK before submitting to avoid surprises.

Do you print white ink?

White ink is available on selected substrates (clear vinyl, dark materials, reflective base). Contact us to confirm availability for your project.

How long do printed outdoor signs last?

Lifespan depends on substrate, laminate, orientation and environment. Laminated polymeric vinyl signs typically last 3–7 years outdoors; engraved alternatives may outlast printed graphics in harsh abrasion environments.

Can you match my brand Pantone colours?

We aim for close Pantone matches within CMYK print limits. For critical brand work, request a printed colour sample before production.
