UK-based Domino Digital Printing Solutions will launch its new K600i White Digital Print Module at Labelexpo Europe 2017 (Brussels Expo, September 25-28) featuring a new state-of-the-art ink management system designed to provide high reliability while utilizing a heavily pigmented UV-curable white ink. The K600i White is targeted primarily at label and packaging printers looking for a digital alternative to screen printing, offering instantaneous job changes, minimal maintenance, variable-data printing capability and eliminating the need to purchase screens. The solution, said the OEM, is particularly well suited to printing high-definition white text in very small point sizes onto personal-care labels and for other transparent label applications. With variable-data print capability, the K600i White can also be used for promotions – such as personalizing with different names, places and promotional games, providing a real added-value scenario. The module can also be easily integrated into existing PDF workflows.
“It’s widely known in the print industry that there are issues surrounding white ink,” said Philip Easton, Director of Domino Digital Printing Solutions. “The reason it can be problematic is that it’s heavily pigmented. When not in use, white ink tends to settle and thicken, which for inkjet technology can cause blocked nozzles and result in unplanned downtime and higher maintenance costs. We’ve solved this problem with a complete ink system re-design. By adding a new white ink tank to our K-Series printer, and a new ink system which continuously mixes the white ink, we’re able to maintain performance and reliable operation.”
In fact, the white ink system has already been proven in the latest generation Domino N610i seven-colour digital label press, and is now available for retrofitting on existing digital label presses and finishing lines via the release of the K600i White. The K600i White is an evolution of the K600i piezo drop-on-demand (DOD) inkjet system and incorporates two print bars for increased ink laydown at higher speeds. It has an industry standard print width of 333mm (13”) and runs at a production speed of 50m/min. (164ft./min.) or 75m/min (246ft./min.) in lower coverage mode. “With the ability to print high quality, small-font sizes in white text, the system is both a good replacement for screen printing and is substantially more versatile,” Easton added. “Thanks to the digital print capability of the new K-Series system, there’s no need for screens or manual changeovers, which significantly reduces downtime as well as costs. With this latest innovation, Domino is providing faster turnarounds, operational simplicity and overall added value – a much sought-after benefit for most label printers
