The Tresu H5i G3 is designed for automation of special coating applications enabling sheet-fed and web offset printers to save resources while exploiting high-speed coating with full control and no risk of micro-foaming and blisters. With H5i G3 controlling the WB, UV or e-beam coating application, operators can now save resources and exploit the full creative potential of the coating media for creating eye-catching designs and strong branding – also with high viscosity and high flow.

The dual-diaphragm pump circulator – one supply and one return pump – features auto-adjusting and fully automated operations of coating pressure and connected tray level sensors, flow sensors, supply and waste level sensors as well as an optional anilox IR temperature measurement.

Picking up from the proven third-generation Li series coating circulators, the H5i G3 features an unmatched range of opportunities in automation, connectivity as well as level- and pressure control and enables full and automated control of a range of high-quality complex coating applications.

Used in combination with a Tresu chamber doctor blade system the Tresu H5i G3 provides full control of the enclosed circulation from the bucket to the chamber, where the coating fills the cells of the anilox roller. This control pressure technology system from Tresu prevents any contamination of air inside the chamber and eliminates micro foaming and undesired blistering of the print.

Tresu’s HMI with intuitive graphical user interface optimizes operators’ start-up times with a fast and easy guide to basic start-up and operation commands and the ability to access a range of automated operation modes as well.

Comprehensive data logging with statistical insights for industry 4.0 operations is now a real opportunity using the ethernet connection of the Tresu H5i G3. Furthermore, the entire platform of the new circulator is 100% modular and ready to adapt to future needs and modes of operation by unlocking already built-in additional features on demand.

Henrik Kristensen, vice-president, Tresu Ancillary, comments, “The H5i G3 makes an important contribution to production efficiency and automation of advanced coating applications and is the optimal solution if you have both high viscosity and high flow volume requirements. The H5i G3 is easily retrofitted into existing coating applications as a stand-alone product or integrated inline into the latest designs of OEM coating solutions with full software integration.”

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.
