Durst has expanded the application fields of the Tau 330 digital UV inkjet print system for the food industry and fully automated industrial production. The Tau 330 now offers a new high definition print mode with print resolutions up to 720 x 1080 dpi. This new production mode improves the print quality, providing sharp texts and fine details in graphics and images.
Tau 330 can now be equipped with 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 (EUPIA) 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, yogurt lids and many more. For these types of materials, Tau 330 is now available with a built-in Chill Roller to cool down 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 requirements of the food and pharmaceutical sector for low odor printing.
Depending on type of application, Tau 330 users may now choose from two different Tau UV inkjet inks: the standard UV Inkjet Inks for all industrial applications or the very new Low Migration UV Inkjet inks suitable for food, healthcare and pharmaceutical applications.
To enhance the productivity with a complete digital end-to-end workflow, Durst says it is presenting a new in-line digital laser finishing system that incorporates laser diecutting technology from Spartanics, with a 1000 watt laser and automatic job changeover to handle multiple jobs in a single run. The die file is generated automatically by the DFE software and downloaded simultaneously with the files for printing directly to the Laser Finishing System and a bar code that is printed with the job is automatically read and retrieves the correct die file where it then automatically starts diecutting the appropriate job. For a complete finishing process, optional UV coating and lamination can be added.
