UV Printing: An Emerging Technology In The Packaging And Printing Industry 12074

What is UV Printing?

UV printing is a method of digital printing that makes use of ultraviolet light to cure ink and dry it as it is spread on the substrate. The ink is dried instantly by the Ultraviolet Lights that follow the printer as it passes over each spot.

Ultraviolet printing allows for direct printing onto a wide variety of flat and 3D media. This makes it possible to customize products. This is why it is so popular among packaging solutions companies. When UV ink is printed onto a substrate, and it is exposed to ultraviolet light it immediately solidifies.

How does it work?

Inks with special solvents are used in traditional printing. They evaporate into the atmosphere when they are applied to the material. These solvents evaporate into the air, allowing ink to soak into the surface faster and leaving behind a digital image once it has dried. Spray powders can be used to speed up drying. However, this printing technique is not compatible with plastics, acrylics, foil, and other materials.

Ultraviolet (UV-) Printing Process

UV printing utilizes ultraviolet lights to dry the ink as it's printed quickly. The printer applies the ink to the surface of the material. After that, the UV lights dry it quickly. Ultraviolet printing is currently a trending topic within the printing sector and is more sustainable than conventional techniques.

UV ink can be printed directly on the substrate (material), and it transforms almost instantly from liquid to solid when exposed to UV light. As there's little evaporation of solvents and almost no absorption into paper, you can print virtually anything with UV inks. This technology provides direct printing capabilities onto an almost limitless range of 3-D media, enabling quick and effortless product customization.

UV inks dry quickly, leaving no VOCs behind. UV printing is an environmentally friendly technology that has a low carbon footprint.

LED UV Printing

Led-UV printing is the latest generation of UV printing technology, producing wavelengths at 385-395nm (nanometer). This light spectrum is safer, more efficient and provides superior results than traditional UV Find more info printing.

Printing with led UV is a more practical choice than its UV counterpart. First, unlike UV printing which requires mercury lamps to cure the inks, led UV does not require them. This makes it safer and more affordable. The UV-A spectrum is where the UV light is emitted, making it safer than traditional UV printing. Additionally, it consumes less energy than traditional UV printing.

LED UV printing offers the long-lasting quality that luxury businesses strive for. Furthermore, its faster drying time gives it greater reliability in the pharmaceutical and FMCG industries. Customers get color enhancements on the final printed products with superior finishing that leaves a lasting impression on buyers.

LED-UV printing can be considered a sustainable and green technology. It emits no volatile organic compounds (VOC) during printing. Companies require less infrastructure to set up LED printing units, while consumers get a superior product with a glossy finish.

UV Printing in Food Packaging Industry

Digital UV printing is an excellent way to personalize products and keep them competitive in a global market.

Conventional printing techniques were dangerous as food items could become contaminated if ink substances were transferred from the printing plate onto the packaging. These inks were not cured, so they could be contaminated. Also, the final food packaging was not up to standard.

UV printing in the food packaging industry has proven a hugely successful solution--UV inks cure during printing, leaving no hazardous solvents that could contaminate what's inside. More and more food manufacturers are pursuing this technique for customized food items while upholding high-quality standards.

UV Printing in the Pharmaceutical Industry

Labeling is unique for every industry. Different industries require different printing technologies. Every brand has its own aesthetic appeal. UV printing is one type of security printing popular within the pharmaceutical sector.

Uniquely, pharmaceutical labels such as medical and drug brand names can be susceptible to counterfeiting or forgery. For added protection, the pharmaceutical industry uses UV printing.

Pharmaceutical printing uses invisible UV inks. This has been shown to be one of most effective techniques to prevent counterfeiting in the pharmaceutical sector. While these inks cannot be seen with the naked eye, they can be illuminated by Ultraviolet LEDs. Invisible UV inks are a powerful deterrent to counterfeiters because they have unique identification numbers attached each time a pharmaceutical item is opened.

UV Printing Offers Untold Advantages

Grand Prints argues that ultraviolet printing is the future of packaging and printing. It is economical and environmentally friendly, and its business-generating advantages are vast.

LED Print Applications: LEDs provide a cool and dry touch with minimal heat output, making them ideal for printing on heat-sensitive substrates such as self-adhesive sheets, thin slides, or stretched PVC materials.

UV Printing Is Faster Than Traditional Printing: UV printing is much quicker than conventional printing, as you don't have to wait for your ink to dry as UV ink dries during the photochemical process - it's almost instantaneous!

It is economical: This method can help you save significant money because of its quicker drying time. You can print more because the finished product dries quickly. Aqueous coatings don't need to be applied as often as traditional inks used for packaging printing.

Bright Finish: UV printing gives you a vibrant look because the ink doesn't have to soak into the material/paper. This method can produce photos-realistic prints.

The Bottom Line

UV printing is a new industry trend which promises to grow over the next few years and have applications in many industries. It is expected to be the future of packaging technology and printing technology due to its cost-efficiency and eco-friendliness.
