Digital UV printing is different from conventional printing in many ways. Instead of having water in the ink that evaporates in the air or is absorbed in the substrate, the UV inks are dried (cured) through a chemical process forming a film that adheres to the substrate.

In the last five years there has been a revolution in digital inkjet printing: UV technology Thanks to the development of cold-curing LED lamps for UV inks, they have opened the door to a wider range of materials that support the direct printing

Historically, inks that are cured by exposure to ultraviolet (UV) light have been used in graphic arts, for applications ranging from packaging to industrial processes; applications for which conventional processes such as lithography, screen printing and flexography can be used.

With the recent introduction of UV-LED lamps, and digital printing technology, the process is expanding its spectrum of applications, especially in the industrial field.

Some advantages
Compared to traditional UV inkjet printers, digital UV-LED printers feature low power consumption, miniaturization, long lifespan, adjustable light intensity, no overheating of materials and no ozone.

In recent years, mass production has reduced the original economic cost of UV-LED units. Currently, the cost of this technology is lower than that of mercury lamps, and thanks to its many advantages, the use of this system is destined to increase within the sector.

UV LED technology allows you to maximize your profits, be versatile, contribute to the care of the environment and the health of the operators of the printers, among other benefits.
