In mid-November 2021, DKSH, the company that sells Soma CI flexo presses in India and most of Asia, together with TEG Technologies, conducted a technical webinar on the optimization of flexographic printing for flexible packaging and labels. The main focus of the webinar was to ensure the growth of packaging demand with greener technologies. The Girona-based firm also used the occasion to introduce the Sitexco Label solution, which will be accessible in the Indian printing and packaging market next year.

Suhas Kulkarni, general manager Asia Pacific of the DKSH PPC Technology business unit, started the session by welcoming the participants and briefly introducing the DKSH printing packaging and converting (PPC) business line. According to him, the Sitexco PLUS System is “the quickest cleaning system in the world, and its proprietary cleaning procedure assures a cleaning that is safe for anilox rolls.” Kulkarni explained that this approach to cleaning and maintenance of anilox rolls could assist converters in both the narrow web and the wide web CI flexo markets. He emphasized the continuous technical development in flexo for rendering even finer print quality and the role of high lineature anilox rolls. A relevant corollary is that anilox cells that have not been cleaned adequately result in clogged cells, and reduced intended ink volume transfer, and poor print densities.

Lluis Guixeras, operations director at TEG Technologies, showed and discussed the latest technologies Sitexco Laser cleaner for anilox rolls and RST solvent distiller. The Sitexco technology is capable of cleaning any ink, coating, varnish, or glue chemical. Guixera talked about its ‘One Pass Clean’ feature. Using its new scanner control allows for complete control of applied energy density, assuring the optimum cleaning performance. The new Laser Cleaner-SLP 2.5 Sitexco Plus is faster, safer, and easy to operate. He also explained the process of how the laser beam and laser spots work and are controlled.

The Sitexco Plus cleaning philosophy is to minimize the damage of the anilox rolls by cleaning them in a single pass. The coatings and deposits that can be successfully removed with this new laser technology are UV, water, acrylic, and solvent-based inks, metallic coatings, adhesive and glues, silicon rubber, and many other types of unwanted materials and artifacts.

DKSH, in collaboration with its partners Popli Graphics for North India and Printers Supply Company for East India and Bangladesh, is ready to assist and give sustainable solutions to the packaging and label printers in India and the Asia Pacific. Mumbai-based Amit Bera of DKSH said, “We have been giving many demos for prospective convertors every month and have had very positive feedback from them about the cleaning performance and outcomes of this technology. We should soon have the first installation of the Sitexco Plus system in India, thanks to the cooperation of TEG Technologies and our local distributor partners in India.”

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 Packaging South Asia’s balanced industry journalism and help sustain us by subscribing.

  1. First off I want to say terrific blog! I had a quick question which I’d like
    to ask if you don’t mind. I was curious to know how you center yourself and
    clear your head prior to writing. I have had difficulty clearing my thoughts in getting my ideas
    out. I do enjoy writing however it just seems
    like the first 10 to 15 minutes are usually lost just trying
    to figure out how to begin. Any ideas or hints?

  2. It’s just a thought process. When you club all the thoughts and have an idea of the theme. Then you can just jot down all the important points.
