Variable data printed using the new K600i White module
Labelexpo Europe will see the introduction of the new K600i White digital print module from Domino. This has been developed as a digital alternative to screen-printing and tackles the issues normally associated with white inkjet inks.
This system features a new ink management system designed to provide high reliability while utilising a heavily pigmented UV curable white ink and is well suited to printing high definition white text in very small point sizes onto personal care labels and for other transparent label applications.
‘It is 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 is heavily pigmented. When not in use, white ink tends to settle and thicken, which for ink jet technology can cause blocked nozzles resulting in unplanned downtime and higher maintenance costs.’
He continued, ‘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.’
This white ink system is already used in the latest generation Domino N610i seven-colour digital label press, and now becomes available for retrofitting on existing digital label presses and finishing lines via the release of the K600i White.
It is an evolution of the K600i piezo drop-on-demand inkjet system and incorporates two print bars for increased ink laydown capability at higher speeds. Printing in a width of 333mm, production speed is 50m/min or 75m/min in lower coverage mode.
