An effective print – whether it be a brochure or catalogue – can make or break a sale, especially when it comes to luxury products. And, according to B&BPRESS, luxury is where UV LED printing truly shines. In UV LED printing, heat no longer plays a part in the drying process. Instead, it’s all based on photochemical reactions – light.
This image by Adhesives & Sealants Magazine illustrates provides a quick overview on the science behind UV LED printing. The UV LED exposure causes a chemical reaction in the applied liquids – inks, coatings or adhesives. The exposure causes a chemical reaction in the liquids, making them harden instantly. Thanks to its consistency, the speed of the process, and the ability to print on a wide range of papers and materials, the method is perfect for luxury printing.
Now that we roughly understand how the technology works, what does it deliver besides increased consistency and speed? According to Koenig & Bauer, a whole lot. The world’s oldest still-active printing house has been one of UV LED’s pioneers, and sees the technology as the wave of the future.
These are just a few of UV LED printing’s benefits mentioned by Koenig & Bauer:
• Higher production speed
• Improved print quality on uncoated papers
• The elimination of odours and heat input into the substrate
• Waste and energy savings
• Reduced powder and coating consumption
• Less need for cleaning of post-press machines
