W&H and Flint Group deliver most difficult print jobs in top quality at high speed
At K 2019, Windmoeller & Hoelscher, a specialist for extrusion, press and converting machines in the flexible packaging market, presented new developments in iii areas: efficient production, sustainable packaging and Packaging 4.0.
Customers attended print demonstrations with the newly introduced flexographic printing printing, NOVOFLEX Ii, at the new Technical Eye at Lengerich. The NOVOFLEX II is W&H'due south press for maximum productivity through high functioning and fast job changes and a speed of upwardly to 800 g/min.
"With a completely new design of the print deck with a very strong arrangement of rollers and impression cylinder, nosotros have reduced vibrations and related problems to a new marketplace standard. This enables elevation quality impress results at very high speeds even with critical vibration inducing images," explained Hermann Veismann, general manager – Business organization Unit of measurement Printing and Finishing, W&H.

"Nosotros started with a articulation project team of Flint Group Flexographic and Xeikon Prepress, and really could drive the print quality to a new level for digital flexo plates. Our system solution comprising ThermoFlexX imagers with the breakthrough Woodpecker Nano surface screening engineering science in combination with the nyloflex NEF plates and UV LED exposure met the expectations of W&H and, thus, nicely contributed to the overwhelming success of the print demonstrations."
Friedrich von Rechteren, global commercial vice president of Flint Group Flexographic, added, "It is impressive to meet that W&H confirmed our quality aim for superior results on a state-of-the-art high speed flexible printing press. With our new flexographic system for solvent plate processing, customers can accomplish a new quality level in flexible packaging produced with an open up plate processing organization.

Woodpecker Nano in combination with Flint Grouping Flexographic plates, provide pregnant benefits to our customers with regard to cost and quality and representing a milestone in flexible packaging printing."
The nyloflex NEF plate is a high durometer plate for flexible packaging and labels and is specially developed for cosmos of flat top dots as well equally reproduction of surface screening. The combination of UV LEDs and UV tubes let the definition of various dot shapes and shoulder angles or relief elements. The Woodpecker Nano software enables the output of surface micro structures at imager level, and thus, avoiding the need for costly RIP options. Woodpecker Nano surface screens are perfectly symmetrical and the finest available for LAMs layer digital flexographic plates.
Running the NOVOFLEX Ii flexographic printing press with a speed of 600 m/min, W&H demonstrated the efficient production of a food fashion print design 'Tortillas' with a unique print quality, high productivity and, consequently, lower total cost of print.
