Speaking to Packaging South Asia, Rajendra Joshi, owner of Rajendra Arts, explains the process of plate making in letterpress, “Depending upon the design, a negative film of the respective design is produced. A coated zinc plate is exposed through the negative film with the aid of a lamp. The part that gets exposed to light becomes acid-proof and the other part becomes reactive to acid. After applying the acid the finished block is mounted on the wood and used as a plate for printing. In 1996, offset printing started to pick up in the market but we focussed on some other trends and initiated services in conventional nylon plates that followed a similar process like letterpress. We found the going difficult in the initial year but were able to get a good number of clients in Pune, Aurangabad, Jalna, Solapur and Kolapur regions of Maharashtra.”

“Till 2014 we followed the conventional process but in December 2015 we set up a new plant for digital flexo plate making to meet the demands of label printers in different regions. Our new unit consists of Xeikon Thermoflex CtP and an in-line washer from Kemao, a firm based in China. For printing, we use Dupont Cyrel plates of 42 x 60 inches that provide high quality printing across various segments of packaging.
These plates have been designed to print on various substrates and inks for applications in tags, labels and flexible packaging. Moreover, these plates have an outstanding run length of around 1 million impressions with excellent tonal range,” adds Joshi.

Comparing the conventional and digital flexo plates, Joshi says, “The digital plate making process has eliminated the need for exposing a film, reduced the process time and enhanced print quality. In the conventional process the increasing cost of films and availability of spare parts remains a challenge which in turn affects print production.”

Rajendra Arts has also opted for StudioRip XF and Pack Z. StudioRip XF is a workflow software for CtPs, proofers and image setters for imposition, trapping and ink duct control modules. Pack Z is the professional editor specially designed for labels and packaging. It is built around the Portable Document Format (PDF) Standard file format to fulfil the needs of packaging graphic design. Pack Z has intelligent algorithms to join single characters into text blocks or detect table structures in packaging. Text blocks are resizeable and text can be copied within the PDF document preserving the style. The edit path tool allows adding and modifying paths such as a clipping path.

Pack Z has the ability to create bar codes such as EAN8 and 13, data matrix and few others. For quality assurance, it tracks all editing made to a PDF document and visualizes them in Edit History palette. The densitometer tool allows accurate measurements to find out the total ink coverage and can deal with CMYK, spot colors, RGB and LAB color spaces. Pack Z automatically detects the areas where trapping can be applied and highlights them. All traps are stored in a database and are marked on a separate layer, which provides easy handling, repeatability and user friendliness. A tool in Pack Z can create registration marks that automatically transform and update when changes are made to design since it is driven by the PDF document
content and its characteristics. The complete package of equipment and software was supplied by Malhotra Graphics.

Presently, the company does not have any plans for further investment. “We have just invested in the new set up and would like to recover this investment first and then think of investing in something new,” concludes Joshi.

Packaging South Asia is the cooperating media partner for drupa 2016 which is scheduled to be held from 31 May to 10 June at Dusseldorf, Germany.

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.
