Mimaki LEDUV Technology Advances Industrial Printing

LED-UV curing systems use ultraviolet radiation to set ink colorants directly on the substrate. The approach is designed to improve operational efficiency while reducing the environmental footprint of industrial print production.

Unlike traditional metal halide curing, LED-UV systems require no long warm-up or restart cycles. The technology also produces less heat, extending the range of temperature-sensitive media that can be printed without distortion.

The system’s main technical characteristics include environmental performance, high throughput, image quality and special-effect capabilities.

• Environmental performance: Low-VOC inks are used, and the LED light source does not generate ozone, supporting environmentally responsible production.
• High efficiency: Print speeds can reach 60 square meters per hour, with broad media compatibility.
• Image quality: Mimaki’s proprietary printhead control technology produces smooth gradations.
• Special processes: White ink can be used as a base layer to improve color expression on transparent media, while primer and color inks can be combined to create embossed, textured effects.

The shift from metal halide lamps to LED-UV light sources changes both the economics and the practical handling of industrial printing. The principal differences concern energy use, warm-up time, heat output, lamp life and ozone generation.

Because of strong media adhesion and curing performance, the technology is used across industrial and commercial settings. Applications range from commercial displays and signage to industrial components, consumer goods and packaging prototypes.

The ability to print on heat-sensitive substrates is particularly relevant for industrial applications where dimensional stability matters. White ink and primer layers further extend the range of usable materials by improving opacity and adhesion.
