White ink issue solved by Domino

White ink has always been an issue in the print industry, due to the heavy pigmentation of the colour. It is also a problem because most inks used for offset printing are translucent, and translucent white ink cannot be printed onto darker paper, making it difficult to offer to customers.

Domino will be showcasing its new white ink module at Labelexpo Europe

Other than the difficulty behind printing white ink, there is also the heightened cost of trying to print it. Presses would have to be thoroughly cleaned by staff, as any ink left on it would ruin the colour of the white. An alternative could be to use opaque white ink, but this would still be costly because several coats would need to be applied to get the correct colour.

However, Domino Digital Printing Solutions has come up with a solution that will allow printers to create the correct shade of white, without all of the accompanying problems. At the Labelexpo in September 2017, the firm will showcase its new K600i White digital print module. It features a new ink management system, which will allow pigmented UV curable white ink to be printed easily.

Philip Easton, director, comments: “It is widely known in the print industry that there are issues surrounding white ink. The reason it can be problematic is that it is heavily pigmented. When not in use, white tends to settle and thicken, which for ink jet technology can cause blocked nozzles resulting in unplanned downtime and higher maintenance costs.

We have solved that problem with a complete ink system redesign. By adding a new white ink tank to our K-Series printer and a new ink system which continuously mixes the white ink, we are able to maintain performance and reliable operation

“We have solved that problem with a complete ink system redesign. By adding a new white ink tank to our K-Series printer and a new ink system which continuously mixes the white ink, we are able to maintain performance and reliable operation.”

A digital alternative to screen printing, the K600i can be added to the existing digital label presses and finishing lines from Domino.

Easton finishes: “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. Thanks to the digital print capability of the new K-Series system, there is no need for screens or manual changeover, 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. We are expecting the K600i White will be well received by the industry and look forward to exhibiting it at Labelexpo Europe.”
