Hönle Group to show UV curing systems at Labelexpo

At Labelexpo Europe on stand 7L75, Dr. Hönle AG and rotary printing specialist PrintConcept will display their UV products for label printing and narrow web applications.

On show will be Hönle’s Uvaprint series of UV dryers, machines available with many options and, due to their compact design, suitable for inkjet applications. The Hönle pureUV is a latest generation UV dryer. Specific design and patented reflector geometry prevent direct radiant heat from reaching the substrate. In addition, the unwanted IR ranges are accurately filtered out. Altogether, this leads to a high intensity irradiation with a minimal temperature load and makes the pureUV suitable for curing temperature-sensitive materials.

The UV system PC1-A-ECO by PrintConcept is suited to label and narrow web applications between 150 and 550mm. It is said to guarantee a highly effective curing, even of temperature-sensitive substrates. The ECO-systems are available with air- or water-cooling.

The LED Powerline is a water-cooled line for intermediate curing (pinning) and final curing for inkjet printing. It is highly intensive and has an external control system. Due to its low weight and its small dimensions the LED Powerline can be integrated even in smallest installation spaces.

In new developments, the LED Powerline is now available in different lengths. Hence, the basic size of 76 x 10 mm can be optionally extended in 40mm steps. Each Powerline is divided into segments of four which can be activated independently from each other. Each segment is electrically driven by a compact and efficient integrated module for cap rail mounting.

PrintConcept will show an inerted UV system for low migration inks. The latest generation of nitrogen-inertization by PrintConcept is characterized by a flat inert-chamber and precise measuring technique. Nitrogen is uniformly distributed within the inert-chamber. A high-speed-inertization reduces the concentration of photoinitiators and thus reduces migration in food-package printing. A special characteristic of the PrintConcept technique is that air- or water-cooled UV units can be easily retrofitted with nitrogen-inertization.

Another highlight at the Hönle Group stand will be a live presentation of an inkjet LED-curing in inert atmospheric conditions on a roll-to roll printer in collaboration with Solex of Nuremberg, Germany.
