Inking system for sheetfed offset presses

CRON showcasing EZcolor

At drupa CRON is demonstrating the new EZcolor system which not only reduces waste and enhances quality but also brings down the point at which short-run offset becomes profitable

Inside the EZcolor enclosure, high performance, micro-pumped ink jets exactly meter ink directly onto the first forme roller. Control of the jets is via CIP3/CIP4 data working in conjunction with an Expert database which predicts the exact ink demand under specific printing conditions. The resulting control over ink volume, to a tolerance of +/-1%, keeps a balance of ink-feed and consumption, hence ensuring a higher color consistency on all printed jobs. Also guided by the Expert database, precise pre-inking on each press unit ensures that makeready is exceptionally fast and that color is accurate after just a few impressions. These advantages give offset users an enhanced capability to compete with digital print for low print runs.

EZcolor ensures greater accuracy for light coverage areas where minor ink variations can make dramatic visual differences to image quality as the volume of ink is exactly metred to match the density requirements for each zone of the printed signature. Full-digital ink control of EZcolor also avoids impacts from unstable conditions, such as ink viscosity, temperature, humidity, press running speed and anything that may affect ink transfer in open fountain systems.

EZcolor is extremely easy to use due to its creative design and intuitive operation. The heart of the system is an enclosed manifold which replaces the cumbersome ink duct on a conventional offset press. Being enclosed the EZcolor system eliminates ink contamination and the problems associated with open fountain systems of viscosity changes through solvent evaporation. There is also no need for an agitation system to keep the ink fluid.

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.

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.
