Label Paper Printing Guide: How to Work Efficiently with a Label Supplier

Want sharp, accurate, professional labels on the first run? This guide walks you through the essentials printers expect—color mode, resolution, file formats, bleed/trim, materials, finishes, and proofing—so you can hand off files with confidence and avoid delays.

Label paper printing guide by DtopLabel—how to work efficiently with a label supplier: color mode, file formats, resolution, proofing

1) Choose the right label material

Your substrate changes both the look and durability of your label.

  • Coated paper – crisp text, cost-effective for retail.

  • PP synthetic paper (polypropylene) – tear-resistant and water-resistant.

  • Pearlescent film – elegant shimmer for beauty & boutique products.

  • Clear/transparent film – “no-label look” on bottles and jars.

  • Metallic variants: gloss silver, matte silver, satin silver – premium, reflective effects; great for tech and cosmetics.

Tip: match the material to real-world use (water/oil exposure, squeezable containers, outdoor sun/heat).

2) Pick your print finish

Finishes add protection and visual punch.

  • Lamination (gloss/matte) – scuff-resistant, adds rigidity and sheen (or a soft-touch matte).

  • Hot foil stamping – mirror-metal accents (gold/silver/rose gold, etc.).

  • Raised varnish (high-build) – tactile, glossy highlight on logos/text.

  • Spot UV – high-gloss pop on selected areas.

Action: In your artwork, clearly label the required finishes (e.g., separate layers named “Spot UV”, “Foil Gold”). It speeds prepress and prevents miscommunication.

3) Color mode: CMYK, not RGB

Screen color (RGB) is more vivid than print color (CMYK). When an RGB file is printed, it must be converted to CMYK, which can cause color shifts.

  • Set files to CMYK before you start designing.

  • If you must convert from RGB, soft-proof in CMYK and tweak critical brand colors.

4) Resolution: keep it sharp

For clear, detailed printing, use 300 dpi or higher at final size.
Avoid upscaling tiny images—start with high-resolution assets to prevent blurry results.

5) Bleed, trim, and safe area

To achieve edge-to-edge printing without white slivers:

  • Add 3 mm (≈1/8 in) bleed on all sides.

  • Include trim lines (the cut path).

  • Keep text and logos inside a safe area (≥3 mm from the trim) to avoid accidental nibbling during die-cut.

If you’re supplying the dieline, place it on a separate spot-color layer named “Dieline/Cut”, set to Overprint, and don’t include it in printable CMYK artwork.

Convert text to outlines and common finishing options—lamination, hot foil stamping, raised varnish, spot UV

6) File formats printers prefer

Provide one of the following: AI, PSD, CDR, PDF, PNG, or JPG.
Whenever possible, export a print-ready PDF with embedded images, outlined fonts, correct bleeds, and trim marks.

7) Convert text to outlines (and share fonts if needed)

Before handing off, convert all text to outlines so fonts won’t reflow or substitute on another computer.
If the design contains heavy text and you expect edits, also send the .OTF/.TTF font files to maintain consistency.

8) Proofing: check before you print

  • Soft proof (on screen) for layout and prepress checks.

  • Hard proof or press sample when color-critical—especially on specialty materials or with metallic/spot finishes.
    Sign off on the proof to lock scope, budget, and schedule.

9) Handover checklist (copy/paste)

  • Document color mode CMYK

  • Images ≥300 dpi at final size

  • 3 mm bleed + trim marks + safe area

  • Finishes labeled on separate layers (Spot UV / Foil / Raised Varnish)

  • Dieline in its own spot color, set to Overprint

  • Text outlined (and fonts attached if edits are needed)

  • Exported PDF + editable source file (AI/PSD/CDR)

  • Approved soft/hard proof

10) Work efficiently with your label supplier

  • Share use case & environment (oil/water exposure, outdoor sun, temperature).

  • Confirm adhesive (permanent, removable, freezer-grade) and core/roll specs (if machine-applied).

  • Provide quantities, deadlines, and budget range early for the best pricing and schedule.

  • Keep one point of contact and consolidate feedback to reduce rounds.

Final word

Great label print results are 80% preparation. With the right material, finish, CMYK setup, 300-dpi images, 3-mm bleed, and clean print-ready files, you’ll get exactly what you expect—without rework, delays, or surprises.

Great results are 80% preparation. Choose the right material and finish, work in CMYK, keep images at 300 dpi, add 3 mm bleed, export a print-ready PDF, and approve a proof—and you’ll get the label you expected without rework.
