Researchers at Fraunhofer IKTS developed a robust solution for the individual labeling of components and products. It withstands extreme environmental influences, can be applied within seconds and read-out reliably. Therefore, the new development is suitable for the integration into industrial plants.
Many raw materials and semi-finished products are exposed to extreme conditions in manufacturing processes or in application, for example high temperatures in metal processing or the glass and ceramics production.
In other areas, such as the leather industry or cleaning processes in the food and pharmaceutical branch, aggressive chemicals are used. Even climate and environmental influences place special demands on the surface of workpieces.
Such extreme conditions can hinder or even render the use of an individual component labeling based on barcodes or matrix codes over the entire process chain impossible. The reasons for this are varied, for example an insufficient thermal and chemical resistance of the codes, a lack of contrast and readability or corrosion during the application of the labeling.
To meet these challenges, researchers at Fraunhofer IKTS developed the CeraCode® technology. It is based on ceramic luminescent materials for inkjet printing. These materials display a pronounced luminescence in response to optical excitation, for example by UV radiation.
For an individual labeling, a special ink with luminescent materials is being printed onto the component. Implemented as barcode or data matrix code, the labeling provides a high contrast to the subsurface, regardless of ambient conditions. The ink shows excellent adhesion to various materials and is highly resilient both thermally and chemically.
“The applicability and robustness of CeraCode® has already been successfully demonstrated in the laboratory and at first pilot customer facilities. The focus of current IKTS research is on the integration of the labeling solution into existing processes. We succeeded in printing series components in the shortest possible time of less than 100 ms“, explains Dr. Thomas Härtling, scientist at Fraunhofer IKTS.
Today, the institute is able to offer a complete solution, ranging from the development of process-suitable ceramic inkjet inks to the generation and printing of the necessary codes and the adjustment of appropriate readers.
From April 25–29, 2016, IKTS researchers answer your questions in Hall 6 at Booth B16.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
