The more high-tech you go, the more these criteria have to be made a reality – indeed, they are practically inseparable from each other, and the foundation for successful and sustainable innovations. Bobst has developed the Mouvent Cluster based on these exact principles.

In inkjet, utilizing the advancements of 3D printing technology, it is able to develop such a compact and effective printing device. A Mouvent Cluster is a unit comprising four inkjet heads and their ink control system, encapsulated in one very compact design. And compactness is not only a size advantage. It indicates that there are minimum moving parts, well-positioned internal elements and precise organized cables and connections.

Unique design logic brings unique advantages

Fewer moving parts mean less maintenance and less risk of failure. But the precisely positioned internal elements mean faster and more accurate temperature control and shorter distribution lines of fluids (less temperature loss and pressure equalization).

In addition, the embedded ink and temperature control units of the Mouvent Cluster follow a very simple architecture rule. Each unit is autonomous, and each inkjet head is controlled in a separate closed-loop, with its own individual pressure and temperature control systems.

This is a radical technology shift in the inkjet world, leading to full jetting control which provides total independence on the speed of printing, ink coverage or levels of details of the printed file.

The main advantage of controlling the ink in such a short distance from the jetting and in a closed-loop manner is the consistency of the ink drop size and the efficiency of the system in long production shifts.

It also enables the elimination of ink mist, absolute print head temperature control and uninterrupted production without the need for pauses to clean or cool down.

Connectivity is also a fundamental design principle for reliable performance. Performance is based on on-the-fly data analysis and algorithmic calculations, which leads to strong control and immediate adaptation.

Simply described, the cluster system has its own modular advanced intelligence to readapt when and where needed and at the same time is connected to a high-speed mainframe and image data stream.

The brain of the system, the electronics, is a fully programmable system. The system was built with a deterministic compute approach, scalable performance, low power consumption and functional safety considerations.

Updates and adaptations can take place directly on the press and triggered even by remote support engineers, ensuring that the technology will always deliver on its promise. So, Bobst Cluster technology is taking inkjet printing to the next level, opening new horizons in the packaging industry.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.

It is the right time to support our high-impact reporting and authoritative and technical information with some of the best correspondents in the industry. Readers can power Indian Printer and Publisher’s balanced industry journalism and help sustain us by subscribing.
