Durst shows Tau with in-line laser

Durst launched its Tau LFS 330 (Laser Finishing System) UV inkjet press into the US market. The Tau LFS 330 integrates a Spartanics laser die cutter into a Tau330 press line specified with a powerful 1,000- watt laser. The RIP is optimized to automatically deliver the cutting profile to the laser without manual intervention, and synchronizes press and cutting speeds.

Durst demonstrated its low-migration (under 10ppb)/ low- odor inks developed in partnership with Sun Chemical’s Sunjet division. These extend the press’ capabilities into the primary food packaging and pharmaceutical segments. A nitrogen inerting unit suppresses the oxygen that creates the odor associated with UV curing.
‘Now we are running at speeds up to 157 feet per minute, in-line finishing now makes sense,’ explained Helmuth Munter, Durst’s worldwide product manager.
The Tau 330 was demonstrated in its new High-Definition print mode, delivering 1260dpi resolution, achieved by switching from variable dot to binary mode with new dot placement algorithms.
Munter answered the question why LED-UV curing has not been adopted: ‘The absorbtion spectrum of our Low Migration inks is different to the peak spectrum of LED, so we would have to slow down the press speed and put in a lot of LED light. Until LED matches better with the peak of low migration inks, this is not an option for our press. ‘
