At the ITMA 2011 trade show, Durst, the specialist in industrial inkjet applications, is presenting a genuine alternative to flatbed screen printing: the Kappa 180. The high-performance inkjet printer achieves a printing speed of more than 600 m2/hour (over 300 running meters) with outstanding printing quality (1056 x 600 dpi), thus enabling the on-demand production of between one and many thousands of running meters.
From the printheads to the ink, the Kappa 180 has been developed by Durst itself with the aim of ensuring optimal image quality and dependability. Together with RIP specialist Caldera, Durst has developed the workflow software for Kappa 180 further in order to speed up printing orders from the design stage to the final print while providing full cost transparency.
Christoph Gamper, Executive Vice President of Durst Phototetechnik AG, says that "with Kappa 180 we are setting the benchmark in digital textile printing at this year's ITMA – not only on account of the impressive technical specifications, but also because we are offering a complete system that provides genuine value added across all production levels. With Kappa 180 and the tailormade Caldera workflow solution, we are supplying our customers with numerous advantages compared with conventional printing methods: total flexibility, time and cost savings, less consumption of resources, environmental friendliness, and a high degree of customer satisfaction."
The Kappa 180 inkjet technology opens the door to completely new creations, since there are no limits as far as design or colors are concerned. Unlike conventional printing methods, there are no pre-printing processes – printing orders and changeovers are processed directly via the workflow software, setup times and screenmaking are things of the past, and the system is ready for printing within a few hours. Water consumption during the production process is reduced by up to 90 percent and only a fraction of the chemicals normally used are required. In addition to these environmentally friendly and cost-effective benefits, printing orders remain reproducible at all times.
Durst Kappa 180 – everything from a single source Printheads: Durst's proprietary Quadro printhead technology was developed further for the Kappa 180, so that the specific requirements of the textile sector could be fulfilled with "QuadroZ". The modified Durst QuadroZ Array system makes it possible to print on textiles with water-based inks by way of a specially hardened, frayresistant nozzle plate with a drop size of 7-21 picoliters. 6,144 jets per color produce a resolution of up to 1,680 dpi, while a single automatic nozzle cleaning system ensures uninterrupted operation. The QuadroZ Arrays print eight colors in CMYK, orange, red, blue and gray with no modulations or density fluctuations. A key role is played here by the ink delivery system with the osmosis filtering system, which eliminates the tiny gas bubbles in the inks and ensures that the printing is steady and failure-free.
