What is the difference between optical grating and reverse UV printing?
When it comes to high-quality packaging, particularly for cosmetic and luxury products, the finishing is extremely important for brand presentation and product attractiveness. Optical grating and reverse UV printing are among the most eye-catching additional methods. Despite the similar effects they create on the surface, they have very different applications, procedures and outcomes.

1.What is Optical Grating?
Optical grating, also referred to as light diffraction or lens embossing, is a technology whereby micro-patterned textures (grating lines) are stamped onto a given material's surface using a special die or mould. These patterns refract light, creating a moving rainbow or 3D-like effect when viewed from different angles.
Visual effect: iridescent holographic shimmer
Touch: is sometimes a bit raised or rough
Ideal in: Counterfeit prevention enhancement, luxury cosmetics, perfumes and gift sets
Process: hot stamping, or grating mold embossing
It reflects the light and gives it a dynamic, luxurious touch that is subject to motion.
2.What is Reverse UV Printing?
The contrast printing technique called Reverse UV Printing combines glossy and matte finishes in a single design. It begins with a gloss-covered surface (such as lamination or varnish), onto which UV varnish is selectively sprayed using screen printing. Once cured, a matte pattern will appear on a glossy background, or vice versa.
Element of appearance: Matte and gloss have a slight contrast in visual appearance
Touch: Velvet with a little bit of texture Feeling: Velvet with a little bit of texture
Best to use: Modern packaging, accentuating the logo designs and effects of texture
Process: Screen print UV oil over gloss or matte lamination
It is both classy and sophisticated, making it perfect for brands that want an understated elegance.

4.Which Should You Choose?
Optical grating is ideal if you want something that is graphically active and beautiful to look at. Hence, a high-end package, limited edition or high-priced product should feature optical grating.
Select reverse UV printing if you want a low-key, designer appearance with a high-brow to low-brow texture message.

About Printing Craftsmanship
What is screen printing used for?
Screen printing is ideal for printing on a variety of surfaces, including:
Fabric (t-shirts, tote bags)
Plastic (bottles, packaging)
Paper (posters, packaging)
Metal and glass (signs, promotional products)
What factors should I consider when choosing a printing technique?
Material: Some methods work better on specific surfaces (e.g., screen printing for fabric, offset for paper).
Budget: Offset is cost-effective for large runs, while digital printing is better for short runs.
Aesthetic & Finish: If you need metallic effects, choose hot stamping; for texture, consider embossing.
Durability: UV printing and screen printing offer long-lasting prints resistant to fading.
What is the difference between offset and digital printing?
Offset Printing: Best for large-volume production, offering high-quality prints at a lower cost per unit.
Digital Printing: Suitable for short runs, allowing quick setup, customization, and fast printing.
