Eyewear Marking Processes (LOGO / Model / Text)
Common processes include pad printing, screen printing, laser engraving, hot stamping (gold/silver), metal logos, UV transfer printing, etc. They suit different materials (metal, acetate, titanium, plastic) and aesthetic requirements.
1. Pad Printing – Most Common
Principle: Etch artwork on steel plate → silicone pad picks up ink → transfer to eyewear surface.
Application: Metal frames, acetate, titanium, temples, lenses; curved surfaces & small areas.
Advantages:
? Rich colors, suitable for small text & fine patterns
? Adapts to irregular curved surfaces, good adhesion
? Moderate cost, suitable for mass & small-batch production
Disadvantages: Average scratch resistance, prone to wear.
2. Screen Printing
Principle: Ink passes through mesh stencil → squeegee application → ink curing.
Application: Flat & large surfaces (lenses, front frames, flat temple areas).
Advantages: Thick ink layer, vibrant colors, strong coverage, wear-resistant.
Disadvantages: Difficult on curved surfaces, small text tends to blur, slow plate change.
3. Laser Engraving
Principle: High-energy laser etches the surface → creates indentation or color contrast.
Application: Metal, titanium, acetate, buffalo horn; high-end branding & permanent marking.
Advantages:
? Never fades, scratch-resistant, eco-friendly (ink-free)
? High precision, fine lines, supports complex patterns
Disadvantages: Monochrome (natural/dark only), high cost, no color options.
4. Hot Stamping (Gold / Silver)
Principle: Heat-activated die transfers gold/silver foil onto the surface.
Application: Acetate, plastic, metal; high-end LOGO & decorative text.
Advantages: Metallic luster, premium texture, wear-resistant, high-end appearance.
Disadvantages: Limited colors (gold, silver, red, black), difficult on curved surfaces, high cost.
5. Metal Logo (Metal Insert)
Principle: Etch or stamp metal sheet (copper, nickel, stainless steel) → inlay or glue onto frame.
Application: High-end metal frames, titanium frames, acetate.
Advantages: Strong texture, permanent, luxurious, three-dimensional effect.
Disadvantages: High cost, complex process, not ideal for tiny text.
6. UV Transfer / Crystal Sticker
Principle: UV adhesive with printed pattern → transfer → UV curing.
Application: Flat & curved surfaces, metal, acetate, plastic.
Advantages: High definition, good color rendition, wear-resistant, 3D effect available.
Disadvantages: Relatively high cost, average adhesion.
7. 3D Printing
Principle: 3D print text/LOGO → paste or inlay into frame.
Application: Special shapes, 3D effects, small-batch customization.
Advantages: Three-dimensional, flexible design, highly personalized.
