Durst Phototechnik AG
Hall 7, Booth 117
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 screen-making 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, fray-resistant 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.
Inks: For textile printing applications, Durst has developed its own high-performance inks (Kappa Inks) for the piezo inkjet multipass technology. These are used for printing with absolutely environmentally friendly, water-based dispersion, reactive and acid inks on the different textile fibers by way of the QuadroZ Arrays. The characteristics of Kappa Inks are deep black, outstanding luminosity and excellent stability.
• Kappa Ink R (Reactive Ink System) for cotton and cotton mixtures with more than 60% cotton
• Kappa Ink D (Dispersion Ink System) for synthetic fibers, polyester and polyester mixtures with more than 50% polyester
• Kappa Ink A (Acid Ink System) for silk and silk mixtures
Workflow: Besides the printing machine itself, the RIP is the most important and also the most error-prone component in the printing process. For this reason, Durst - together with specialist Caldera - has developed GrandRIP+ software for digital textile printing, tailoring it to match the Kappa 180.The speedy, reliable and high-performing workflow solution encompasses all the functions required for the creation and management of printing orders. These include such features as tiling, embedded color profiles and ICC-compliant output, Photoshop plug-ins, coloring and color coordination of textile print data, a dashboard with a preview function and rapid access to printing orders, multitasking control for distributed printing machines and enhanced ink management. The digital printing data can be collated and configured individually by means of the layout & compose function. To this end, GrandRIP+ supports the standard image formats EPS, PS, PDF, JPG, Photoshop and TIF.
Transparency: The Kappa 180 Costview software ensures precise calculation of the production costs and environmental factors for each printing order. All relevant parameters, including ink, material, power and other factors, are analyzed via a dashboard, while at the same time the CO2 emissions are calculated for each production stage. Costview has a web interface, which means that all analyses can be interchanged with other departments at any point in time.
Support: With Durst Advanced Remote Diagnostics (DARD™), the Kappa 180 has an innovative remote maintenance and alert system which monitors all relevant parameters, including printheads, humidity, temperature, voltage, etc., in order to maintain an even production process and prevent unscheduled machine downtimes.
Feeding-in: Being a top-quality textile printing machine, the Durst Kappa 180 has fully automatic feeding-in and guiding facilities for textiles with a maximum printing width of 195 cm and a printing blanket with an integrated washing system. The drying unit is a hot air dryer powered by gas, steam or electricity.
Durst Kappa 180 at the ITMA 2011 trade show
Durst Kappa is being premiered at ITMA 2011 and will be demonstrated at Stand B117 in Hall 7 from September 22-29, 2011. Prospective customers can see for themselves the capabilities of the high-performance digital printer and obtain first-hand information about the new product.
