Universal Laser Platform

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 metallized 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 4000 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 advantages:

  • Complete design freedom thanks to true 3D lasering
  • Maximum laser resolution for optimum reproduction of details
  • Undistorted designs thanks to controlled material engraving
  • Fully digital process for 100% reproducibility
  • Two 600 W fiber lasers for maximum productivity
  • Automated process for depths of up to 4 mm
  • Flexible enough for any requirement thanks to intelligent algorithms

Cellaxy and HelioKlischograph in dual operation

In dual operation, Cellaxy and HelioKlischograph engrave together for one color set. The assignment of linework cylinders and halftone cylinders to the machines is completely freely selectable. This means that the processes complement each other perfectly in terms of their possibilities.
