How Does Foil Stamping Work?

(Understand production in just 3 simple steps)

Step 1: Choosing the Right Material

• Polyester: Best for glossy gold foil, vibrant and clean finish
• Cotton & Linen: Matte silver recommended to avoid awkward glare
• Waterproof Coated Fabric: Requires surface treatment (technical term: medium isolation)

Step 2: Compatibility Chart – Fabric & Foil Types

Step 3: Temperature Control

• General Use: Iron temperature ~140°C (feels warm over the hand)
• Detailed Patterns: Heat to 160°C + apply pressure for 3 seconds (stamp-like effect)

Step 4: Final Inspection

• Rub with fingertip 10 times—no color loss
• Hold up to light—check for bubbles, missing edges

Cost Control Formula

• Foil stamping unit price = base ¥0.8 + specialty foil surcharge + labor loss
• Example: 10 cm² logo = ¥0.8 + ¥0.3 (special foil) + ¥0.2 = ¥1.3 per piece
