Why this matters

Missed launches and reprints don’t happen at the press—they start in the brief. This playbook shows you how to move from idea to line-ready packs without drama, using simple decisions that lock quality, timelines, and cost early.

1) Define the job in one page

What to write down (no jargon):

  • SKUs & quantities per variant
  • Primary pack & environment (oils, moisture, light, temp)
  • Regulatory needs (Agmark/pharma, batch/expiry, barcode type)
  • Line info (cartoner style, label cores/OD, COF/seal targets for pouches)
  • Deadlines, delivery plan, and palletization

Outcome: Everyone aligns on constraints before artwork starts.

2) Pick the right print process for the part

  • Cartons → Offset for color fidelity, fine text, special effects (spot UV, foil, emboss).
  • Pouches & Foil → Rotogravure for deep solids, smooth gradients, durable ink anchorage.
  • Labels → Flexo for crisp barcodes, roll-form supply, and tough topcoats.
  • Tubes → Dedicated tube print with accurate seams, heading, and torque.

Outcome: You get the finish you want without over-engineering.

3) Choose substrates by use-case, not habit

  • Mono Cartons: FBB/SBS for premium whites; Duplex for value; add soft-touch/foil for impact.
  • Liner Cartons: PE/greaseproof for oil & moisture; MetPET when light/aroma barrier matters.
  • Labels: Paper for economy; BOPP/films for moisture; metallic films for premium cues.
  • Pouches: PET/PE • PET/ALU/PE • BOPP/CPP • PET/NY(EVOH)/PE—match barrier to shelf-life.
  • Printed Foil: Select lacquer for PVC/PS/PP/PET sealing; confirm peel vs weld.
  • Lami Tubes: ABL for stronger barrier; PBL for squeezability and fully-plastic builds.

Outcome: Packs look right and survive real handling.

4) Make color repeatable

  • Decide brand colors (CMYK builds vs Pantone spots) with tolerances (ΔE).
  • Use PDF/X-1a exports and share profiles.
  • On metallic bases (MetPET, metallic labels), plan white underprints and reveal zones.
  • Approve effect maps (foil, spot UV, drip-off) before CTP.

Outcome: Reorders match the first run—no more “almost right” blues.

5) Design for machines (and humans)

  • Barcodes: high-contrast area, quiet zone intact, no tight curves or heavy varnish over the code.
  • Small text: set minimum sizes for the chosen finish; avoid hairline fonts on metallics.
  • Windows & zippers (pouches): confirm sizes, seal widths, and registration marks.
  • Carton locks: match crease depth and tuck friction to the cartoner.

Outcome: Faster lines, fewer rejects.

6) Proof once, approve with confidence

  • Digital proof → (if needed) on-press check for critical launches.
  • For metallics, sign off on white plates and reveal strategy.
  • Lock eye-marks, roll specs (core/OD), and winding direction for labels.

Outcome: Approvals that stick—no last-minute surprises.

7) Plan finishes where they matter

  • Shelf impact: hot/cold foil on logos, spot UV for contrast, soft-touch for premium feel.
  • Protection: anti-scuff varnish on high-contact areas; lamination for pouches/labels.
  • Cost control: use foil stamping when metallic area is selective; use MetPET for all-over sheen.

Outcome: Money spent where customers actually notice.

Mini win: Fixing slow scans on a personal-care line

We moved the barcode to a matte, high-contrast panel, raised bar height by 12%, and kept a varnish window. Result: read-rate jumped to 99.6% and line speed recovered without hardware changes.

Quick, no-nonsense checklist

  • ✅ One-page brief with SKUs, environment, compliance, and line details
  • ✅ Confirm process (offset/gravure/flexo/tube) and substrate per SKU
  • ✅ Color plan (spots vs CMYK) + ΔE tolerances + white underprint map
  • ✅ Dieline from production—not a mockup
  • ✅ Barcodes verified; quiet zones intact
  • ✅ PDF/X-1a; fonts outlined or supplied
  • ✅ Roll specs (labels): core, OD, web lead, winding
  • ✅ COF/seal targets (pouches) or crease/lock spec (cartons)
