In the rapidly evolving world of industrial printing, UV technology has transcended simple color application. Today, the ability to create tactile, high-value finishes like 3D Embossing and Hot Stamping is a game-changer for businesses looking to stand out. At Rainbow Inkjet, we specialize in providing the tools that unlock these creative possibilities.
This guide explores how to master these advanced effects to elevate your print products.
The Magic of 3D Embossing: Adding a Third Dimension
3D embossing, or relief printing, adds a physical texture to your designs. Whether it's the scales of a lizard on a phone case or an elegant logo on a wooden plaque, this effect creates a premium feel that customers can touch and feel.
Step 1: Layering the Foundation
The "3D relief" effect is achieved through the strategic overprinting of multiple layers of White UV Ink.
- Mechanism: The printer performs multiple passes, applying white ink that is instantly cured by UV light. Each pass builds physical height.
- Precision: High-quality printers like our Galaxy9X Industrial UV Printer allow for precise height control, ensuring the texture is consistent across the entire print area.
Step 2: Adding Color and Gloss
Once the desired height is reached, the CMYK color layer is printed directly on top of the white ink. To finish, a layer of Glossy Varnish is often applied to protect the texture and enhance the color depth.

The Role of Special UV Varnish
The secret to digital hot stamping lies in the Special UV Varnish.
- Selective Adhesion: The varnish is printed only on the specific areas where you want the metallic foil to stick.
- Bonding: This varnish is formulated to act as an adhesive that bonds with the foil under the heat and pressure of a laminator.
