COLOP Heavy Duty Stamp: Our team will perform a basic artwork check to ensure the file is suitable for heavy-duty stamping. This includes checking size, layout clarity, line thickness and overall stamp readability. Minor adjustments may be made if required before proceeding to production.

✅ Quick Upload Checklist (Important)

  • Recommended format: AI or PDF (vector artwork required)
  • Artwork must be BLACK & WHITE only (no colour, no greyscale)

  • Minimum line thickness: 0.3pt (thicker lines recommended for durability)
  • Avoid fine details that may not reproduce clearly on heavy-duty stamps
  • Artwork size must match the selected COLOP Heavy Duty Stamp size
