Successful print tests on Uteco's first LED UV press

Uteco's first LED UV-enabled ultrafast low migration VLF flexo press has passed its print tests and is on schedule for commissioning next month in the press hall of flexible packaging printer La Gerunda Merletti, based in Cremona, Italy.

During the tests – which took place at Uteco’s head quarters the team from La Gerunda was joined by specialists from partner manufacturer Air Motion Systems to see the Uteco Onyx 810 CI deliver excellent performance at running speeds up to 400 m/min.

For La Gerunda, the new Onyx represents a return to Uteco after more than 20 years and followed an intensive examination of the technologies on offer from the leading manufacturers.

According to them, the production runs in this sector can be short so Uteco's patented Direct Drive Evo and Thermilox Anilox solution offer benefits for better productivity, while their more advanced cleaning systems contribute to faster job changeovers with less waste.

The La Gerunda Onyx 810 has been specified with eight printing stations, 1250 mm maximum web width and 1100 mm maximum print repeat cycle. Seven AMS LED UV curing lamps are fitted at the printing stations around the Central Impression drum with the eighth situated at the exit of the web on the top deck. The press has been provided with the housing for a ninth AMS unit, adjacent to the eighth, if La Gerunda should decide, at some time in the future, to upgrade the press to the 500 m/min option with the next AMS LED UV lamp development, the XP Ultra.
