Cellaxy defines the high-end in gravure. Cellaxy also meets the highest embossing and coating requirements. The Cellaxy laser system’s universal design enables adjustments to be made based on intelligent algorithms without any mechanical changes. This ensures the high-power, high-quality laser beam can be utilized to optimum effect in any application.

One feature exclusive to Cellaxy is the use of up to two fiber lasers in the 600 W performance class, making it the most productive direct laser on the market. Thanks to its platform design, Cellaxy can optionally be equipped with any type of laser, meaning it is also prepared for future developments such as the high-performance classes of nano and pico lasers. The necessary preparations are in place for Cellaxy to engrave the HelioPearl laser-engravable monolayer from K.Walter GmbH & Co. KG, too.

Direct laser for linework and text

Cellaxy engraves with a laser spot size of 10 μm and a resolution of up to 2000 l/cm (5080 dpi) for contour definition in etching quality. In addition the special algorithm for optimizing edge cells produces smooth, closed contours in print.

When engraving with Cellaxy, the screen and screen angle have no effect on the speed of the laser. This means Cellaxy can make the most of its superior performance regardless of job structure, imaging a gravure cylinder up to three times faster than an 8 kHz standard engraving machine.

Direct laser for contone

As a result of finer tonal gradations, Cellaxy produces contones that are even more nuanced and show even higher contrast than in stylus engraving. Either a diamond-shaped or a hexagonal screen can be used for contone reproduction. Helio-compatible calculation of contone screens ensures cylinders engraved conventionally and lasered with Cellaxy can always be used together for printing.

Cellaxy works in tandem with CellCreator. This unique software makes it possible to adapt contone screens to specific printing conditions, which also creates smooth vignettes on aluminum and perfect smoothness with metalized inks.


Direct laser for embossing

As a universal laser for the direct structuring of metal surfaces, Cellaxy opens up many applications in the field of embossing.

Cellaxy performs fully automated multipass engraving with an engraving depth of up to 1000 μm. It does so on a variety of materials, including copper, zinc, steel, and aluminum. Both 2D and 3D embossing forms are produced in the highest possible stepless and seamless quality. The results achieved with Cellaxy embossing processes are highly impressive thanks to long-lasting tactile qualities and high attention to detail. This applies equally to micro-embossing over large areas and background textures.

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.
