At the two-day 15th CESS Training Program on Printing and Surface Properties Evaluation of Paper at the Central Pulp and Paper Research Institute (CPPRI), Saharanpur, held on 19 and 20 January 2016, Andreas M Verhoeven, area manager at IGT Test Systems, talked about various problems in print. Highlighting the problems related to substrates and the associated responsibilities to be undertaken while producing substrates, Verhoeven said, “You as a producer of substrate will find slowly more and more environmental regulation from the government. You cannot dump waste water in the river or blow everything in the air. You must use environment-friendly raw material to make your products. This means that you are in the course of continuous learning because everything is changing and this also means that we have been facing problems in printing constantly. Also in printing we see more and more higher TACT (Total Area Coverage of Images) on paper. In the past we found only less amount of images and text. But these days, the complete sheet is filled with colors and it is really a beauty to see. So there is more and more ink on a single page – which means there is higher chance of goof-ups on the page.” Verhoeven also talked about IGT Test System’s history, development on IGT test instruments, and color management and print evaluation.

Verhoeven touched upon various common printing problems such as picking, mottle, linting, roughness, scumming and others. “Picking of paper is the damage of the paper surface during printing operations,” At the time the printing form is lifted off the paper, the ink exerts a certain force on the paper. This force increases with an increase in viscosity and tack of the ink and the printing speed. When this printing speed exceeds a certain value, the surface of the paper will be damaged.

AK Mehra of JK – CPM, Gujarat, gave an overview of printing process, packaging board quality, requirement, common printing defects and possible remedies at the training program. Mehra said, “A printing process describes the method adopted by a system to transfer the image on to a substrate. This also means that a printing system will have a medium that carries the image in the first place before it enables the process of reproduction. Mehra also discussed the expectations of converters. He said, “Converters expect excellent runnability on all machines, good printability and varnishability.” Printability demands are generally smoothness (PPS/Bendsten), flatness, gloss and print gloss, IGT Dry Pick, uniform coating and Cobb while varnishability demands are smoothness (PPS), flatness, Cobb and suitable coating formulation.

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.
