Stork’s intermittent rotary screen module for variable print-lengths


A special feature of the unit is Stork’s patented intermittent-contact squeegee system. This eliminates the problem of mesh-stretching, by only applying downward pressure against the screen, while the mesh makes contact with the substrate. When the screen assumes the off-contact position, the squeegee pressure is immediately disengaged.

Intermittent printing systems enable substantial savings in tooling costs and changeover time. Between impressions, the web realigns itself, by making an intermittent web movement, which is adjustable according to the repeat length. In this way, a single screen or cylinder size can be used for many different print jobs.

The unit features Stork’s patented squeegee system, which eliminates the problem of screen wear-and-tear. Bert Grootjen, program manager graphics at Stork Prints, comments: “The unit has proved so popular because it gives label converters the chance to compete successfully in short-run, high-end markets, while enjoying low consumable costs at the same time.”

Rotary screen printing is seen as a highly productive means of applying thick ink and varnish deposits. As a result, the process is ideal for high-end features that offer extra shelf impact, like high-lustre varnishes, tactile and raised image effects, brilliant opaques, the no-label look, thermo-chromic inks, and a range of brand-protecting security solutions, such as iridescent inks.

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.
