Coatema and Helisonic: Laser Induced Force Transfer Technology

The Partnership - Coatema and Heliosonic are planning a partnership


Stay tuned for the launch of fuelcell2print, our high precision digital membrane coating system integrated

into a world-class web handling infrastructure. Pre-registration for trial days coming soon! 


Key highlights with our partner include a seamless integration of HELIOSONIC print head

with  Coatema's cutting-edge web handling systems, digital fabrication for renewable energy tech, and a

significant leap in printing capabilities, combining speed with unparalleled precision. 


The fusion of Coatema's legacy with HELIOSONIC';s innovations is not just a partnership; it is a call to the future of industrial printing. We invite stakeholders, partners, and customers to join us in embracing

this new era where potential meets realization. 


The Companies  


HELIOSONIC - Printing the Unprintable 


HELIOSONIC uses and develops a laser-based digital printing technology suitable for material

deposition with a large range of inks for several different applications. With this technology, inks that

can so far not be printed digitally can be used, such as high viscosity inks or inks containing large


The principle 

A carrier belt is coated with a layer of the ink. A laser beam is focused into the ink from the opposite

side of the belt. The laser creates a bubble, and, as a result, an ink jet is produced. 

While the carrier belt is moving to continuously supply fresh ink to the printing area, the laser beam is

scanning over the belt. 

Before reaching the scanner unit, the laser beam is passing through an acousto-optical modulator. The

acousto-optical modulator can switch the laser on and off, thus creating the digital image. 

The acousto-optical modulator is digitally controlled, synchronized with the scanner movement. The

patterns for material deposition are given by image files in Tiff-format, that can be designed with any

image processing software.


The jetting mechanism requires the ink to absorb the laser light (typically approx. 1070nm). For inks

that do not absorb at this wavelength, absorbers can be added to the ink.

The benefits 

  • Fully digital technology 

The material deposition is entirely controlled by the print file and the print parameters (such as

laser power, for instance). Unlike screen printers, the HELIOSONIC technology does not use a

print form. This allows for free form deposition with arbitrary shapes, that can be changed at

any time. 

  • Contactless printing 

The print head does not touch the target. Depending on the ink, typical print distances are

200µm to 1mm. Therefore, wet-on-wet deposition is possible. This can be used to increase the

thickness of the deposited layer by running multiple prints consecutively on the same target.

Also, no pressure is applied to the target. 

  • Nozzleless printing 

In principle, the HELIOSONIC technology can be thought of as an inkjet process without nozzles.

Thus, some of the major restrictions of conventional ink jet printers are eliminated. Since no

nozzles can be clogged or damaged, high viscosity inks and inks containing large particles can

be used. 


Coatema – From Lab2Fab

Coatema Coating Machinery GmbH designs and produces Sheet-to-Sheet and Roll-to-Roll equipment
