The primary benefits of UV curable industrial inks are that these inks dry faster, provide a shorter production time, and contain fewer volatile organic substances.
Today, the digital printing sector is going crazy in the UV ink revolution, which means it needs quality industrial UV inks.
UV inkjet has been available for several years in the wire and cable market, but has been limited in the ink market because of the viscosity restrictions of inkjet printheads. However, over the past five years, new printhead designs and technology has improved, enhancing the ability to use UV industrial ink. New industrial inkjet printers have experienced a substantial increase in the range of ink viscosity.
The Benefits of UV Inks
The instant dry feature makes UV inks wildly popular because it aids in leaving the graphic totally cured/set. Therefore, no solvents can penetrate the material after it is taken from the printer. The fast-drying benefit means there are no concerns with adhesion or the ink bleeding into the substrate after printing.
Higher Production and Less Maintenance
UV inks don’t dry on the printer’s printhead, so there are no worries regarding purging or cleaning the printhead. Since you don’t need to wait for UV ink to dry or for solvents to dry, productions rates are improved and printer maintenance is lower.
UV industrial inks also provide consistency between substrates. You can keep printing from substrate to substrate without worrying about getting consistent image/text results.
Did you know that the environmental advantages are part of why UV inks are so popular in the digital printing sector? Because they don’t need solvents, they give off fewer emissions, which is better for the environment.
A New Ink Revolution
Other benefits of UV inks are as follows:
- One-pass curing
- Fade resistant
- Absent of VOCs
- Media independence
- Water resistant
UV curable industrial inks will provide digital printing on a wide range of uncoated media ranging from rigid to roll feed. It will expand the opportunities for graphic printing applications and reduce/eliminate the need for lamination.
UV Ink Methods
UV curable inks are up-and-coming with hot melt, low-viscosity, and water-based methods.
- Water-based – The water-based approach is getting noticed because of its ability to have a low viscosity. The drawback to this tech is the printing system needs to be totally free from water before the UV light cures the ink.
- Low-Viscosity – Low-viscosity UV industrial inks are designed to work with Piezo printheads and the higher viscosity inks are designed for industrial printheads.
- Hot Melt – Hot melt UV inkjet inks rely on a large viscosity droplet and is still in development with UV inks. They may or may not have issues with cracking on flexible substrates or abrasion and wear.
The Future of UV Curable Inks
There are still some challenges and glitches to work out in some of the methods of UV ink production and its application. Costs are a problem as are safety and health issues. However, collaboration and teamwork between industrial ink vendors such as https://www.needham-ink.com/ink-dot/will help make UV curable inks in the digital sector become a safe and reliable reality.
