Ever wondered why some brochures look more stylish and luxurious than others? Well, it might have something to do with UV LED curing. It is one of the best possible printing techniques for designing premium brochures.
Technically, what makes UV LED curing special is its drying method. Unlike the traditional methods, the new technique reduces reject rates, increases production speed, improves solvent and scratch resistance, as well as facilitates bonding.
But how does UV LED curing work in printing? Read on for a detailed insight into everything you need to know about its criterion of functionality in this blog.

What is LED UV Curing?
UV LED curing is a process used in printing that involves using ultraviolet light-emitting diodes (UV LEDs) to dry or cure coatings, ink, or adhesives. In traditional printing systems, ink is dried by evaporating solvents into the air.
However, in UV LED curing systems, the process provides a more efficient and environmentally friendly alternative by using light to trigger a chemical reaction that hardens the ink. As a result, it is made more durable and resistant to scratches, abrasions, and fading.
How Does it Work?
The process used in UV LED curing exposes the printed material to a high-intensity UV light source. This light source activates a photo initiator in the ink or coating, which starts a polymerization chemical reaction.
During the process, the individual molecules of the ink or coating are linked together to form a solid, hard layer. The result is a high-quality print that is ready for immediate use without the need for additional drying time. There is quite a wide range of UV LED curing systems. Some main types include Sheet-Fed Offset LED, Flexo LED, and Intermittent Label Offset LED.
Why Do You Need UV LED Curing in Printing?
Here are some of the benefits of using LED curing in printing:
- Lower Energy Consumption – UV LED curing is more energy-efficient than traditional printing methods. Unlike other types of printing, it uses very little energy, making it a more sustainable option.
- Faster Printing Speeds – UV LED curing allows speedier printing speeds than traditional printing methods. As soon as the UV LED light cures the ink, it is immediately ready for the next stage of the printing process.
- Environmentally Friendly – UV LED curing is an environmentally friendly option for printing. It produces no harmful emissions, making it a more sustainable choice.
- Improved Print Quality – UV LED curing provides better print quality than traditional printing methods. The ink is cured by the UV LED light almost instantly, creating a smooth, vibrant finish resistant to scratching.
Besides, as the printing industry continues to evolve, there is a high chance that UV LED curing will become more prevalent.
Final Thoughts
The technology integrated into the UV LED makes it possible to get high-quality prints that are fast-drying, durable, and environmentally friendly. All you need to do is choose your stock wisely to help you get the best possible results for a luxury brochure to advertise your products.
