The new Cellaxy boasts a variety of new functions. The laser platform concept makes it a particularly secure investment. Cellaxy defines the new high end in gravure. Hell Gravure Systems

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 impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.

In an admittedly fragmented and textured terrain, this is the right time to plan your participation and marketing support communication – in our impactful and highly targeted business platform.
