The project is supported by the state of Saxony and by financial means of the ERFE (Europäischer Fond für regionale Entwicklung).

Janoschka has developed an integrated system for reproducing tactile and semi-tactile structures.

The combination of a state-of-the-arte direct laser system, innovative topographic scan technology and the use of the latest 3D RapidPrototyping technique allow a totally new product dimension. The new system for the packaging and decor industry is being developed at the Janoschka innovation center at the Sächsische Walzengravur/SWG in Frankenberg (Germany) in close collaboration with the Institute of Printing, Processing and Packaging (iP Leipzig, Germany) and the University of Applied Science Leipzig (HTWK, Germany).

The core of the new system is mainly a new printing and embossing workflow, developed by SWG, that is permanently based on digital 3D data (hapticCELL). Congruent printing data with a spatial impression are combined with high definition 3D embossing data strengthening the visual perception of the embossing on one side and giving a more vital appearance to the printing data on the other side.

A software and a topographic scan system separately create the data for embossing and colour and are afterwards mounted to one picture on the system. The spatial effect of the picture does correspond with the one of the original. The high quality of the 3D effect is qualifying the process to be applied for proofing purposes as well.

With very little efforts the data may be used to create tactile surfaces afterwards. The applied innovative RapidPrototyping/3D Print technology allows to test and evaluate the tactile and optical properties of a new packaging or a new decor very early during design stage. Savings in time and cost and huge advantages on the market are sure. The data may also be used to manufacture print and embossing formes.

Embossing and rotogravure cylinders are produced with the most modern laser direct systems. A laser beam of a diameter of about 1/100mm transfers the data directly into the surface of the embossing roller. The laser intensity may be regulated in fine shades and so the designs can be reproduced very truly in their three dimensional structures.

This integrated process is constantly developed and refined supported by different academic papers of the iP3 Leipzig. It is the goal to transfer the high engraving resolution and the data’s detail accuracy onto different substrates (carton, foil, etc.) without losses.
