Europe: Durst demonstrates digital UV inkjet print system at interpack 2014

SHARE

Industrial inkjet company Durst has demonstrated the full range of applications of Tau 330 digital ultra violet (UV) inkjet print system at the interpack exhibition in Düsseldorf, Germany from May 8 to 14, 2014.

The system was launched in early 2013 and 20 of such systems were installed worldwide.

Tau 330 now offers a new high definition print mode with print resolutions up to 720 x 1080 dpi.

This improves the print quality significantly, providing sharp texts and fine details in graphics and images.

Low migration UV inks for primary food packaging

The system can equipped with the new Tau low migration UV Inks from SUNJET to print primary food packaging.

The Tau Low Migration ink components meet all the guidelines of the European Printing Ink Association and the Swiss Ordnance on Materials & Articles legislation and do not utilize materials specifically excluded on the Nestlé Packaging Inks Specification.

The Durst Tau 330 together with this ink will expand the range of suitable applications for unsupported foils, such as blister packs and yogurt lids.

For such packaging materials, Tau 330 is now available with a built-in chill roller to lower the temperature of printed films and foils during the curing process.

Additionally, the newly built-in inert-gas system reduces the typical odor of UV inkjet inks, to meet the requirement in the food and pharmaceutical sector for low odor printing.

Depending on type of application, Tau 330 users can use either the standard UV inkjet inks for all industrial use or the low migration UV inkjet inks for food, healthcare and pharmaceutical.

In-line digital laser finishing system

For a complete digital end-to-end workflow, Durst’s in-line digital laser finishing system incorporates laser die cutting technology from Spartanics and 1000 watt laser.

These tools enable an automatic job changeover to handle multiple jobs in a run.

The DFE software generates the die file that is downloaded simultaneously with the files for printing directly to the laser finishing system.

A barcode that is printed with the job is read and retrieves the correct die file where it starts die cutting the appropriate job.

UV coating and lamination can be added for a complete finishing process.

Optional add-ons

To increase print quality, reliability and production security, Tau 330 can be additionally equipped with a built-into the press high-resolution video inspection system from NIKKA, which detects print defects during printing.

Tau 330 can also be equipped with external unwinder and rewinder units to print big rolls and volumes, as well as other finishing systems, to integrate Tau 330 in any existing production line.

The connection box collects all related signals and synchronizes them with external devices.
