World's First LED UV Install On Web Offset Press "Cures" Heatset Dryer Woes

In this video, the M600 is seen producing 40K impressions per hour.

Printing Impressions recently published an article on the world's first installation of a "light-emitting diode"-based UV drying system on a high-speed web-offset press; the unit is operated by Kinmei Printing in Japan, and the two LED UV modules, which replaced a heatset drying system, were made by Air Motion Systems.


The printer reports that the refresh of the 10-year-old press, which included the installation of two XP9 LED UV components from AMS (one positioned above the web and the other below it), among other tactical upgrades, enables speeds of 40,000 impressions per hour, and they have been actively producing on the revitalized unit since the end of 2015.

In this video, the press can be seen producing 30,000 sheets per hour, and achieving sheetfed-quality on a web offset press.

The update also brings many key improvements in print-product quality and energy efficiency to the table, officials noted.

Among these, the issues the company had encountered due to infrared drying - including cockling, fluting, and browned paper - have been eliminated by the transition to LED UV, and Kinmei said it can now produce sheetfed-quality printing on the offset web press with vibrant ink density on stocks ranging from thin newspaper weights to heavy gloss papers.

The company added that it has achieved a 70% reduction in the press's energy consumption, which has already quickened its ROI.
