Artwork & Layout

• Use the **official CAD dieline** (latest revision) with glue areas and no-print zones marked.
• All **bleeds set to 1/8″ (3 mm)** minimum; safe margins respected around cuts/creases.
• **Live text** kept off folds/creases and at least 1/8″ from cut edges.
• Vector for logos/icons; **raster images ≥ 300 ppi** at final size.
• Linked assets **embedded** or packaged; remove unused layers and swatches.

Color Management

• Choose the print process: **CMYK**, **spot/Pantone**, or a hybrid; specify for each panel.
• Provide a **color target** (Pantone code or approved proof); note acceptable **ΔE tolerances**.
• Convert RGB to CMYK intentionally; avoid rich black on small text (use **K-only**).
• Large solids: add subtle **tints/underprints** if needed to prevent banding/mottle.

Typography & Legibility

• Minimum font size respected (body ≥ **7–8 pt** for cartons; larger for reversed type).
• Convert fonts to **outlines** or include font files; check kerning after outline.
• Avoid hairline rules; keep strokes **≥ 0.25 pt** (or 0.5 pt reversed).

Barcodes & Regulatory

• **GS1 UPC/EAN** sized per spec; quiet zones clear; do not place over creases or high-gloss glare areas.
• For Amazon/marketplaces: **FNSKU** & carton **Box ID** labels reserved on flat areas.
• Medical/device or food: space for **UDI**, warnings, nutrition/IFU, and required symbols.
• Environmental claims phrased per **FTC Green Guides** (or local rules); add recycling icons appropriately.

Files for Press

• Deliver **PDF/X-1a or PDF/X-4**, plus native files (AI/INDD) if requested.
• **Overprint/knockout** settings reviewed (especially on whites and spot colors).
• Varnish/spot UV/emboss **on separate named layers** with 100% spot swatches.
• Include a **1:1 scale mockup** or soft proof; request **contract proof** for color-critical jobs.
