Object of the presented invention belongs to the field of frequency selective screens which act as filters for different electromagnetic radiation frequency ranges. The invention refers to the meta-cells design and their transfer by means of the printing process onto the flexible printing materials. By printing the meta-cells, so called meta-papers are produced, which act as frequency selective screens. The function of the filter for a specific electromagnetic frequency range is achieved by the appropriate shape and dimension of the meta-cells. The invention refers especially to the manufacturing of a frequency selective screen. Printed screens can be used to protect people from a harmful electromagnetic radiation, as well as for data protection or to improve the performance of wireless networks. More specifically, it is about printing of meta-cells on a flexible printing material. Printing can be done roll-to-roll using conventional or digital printing technologies. Depending on the meta-cells shape and size, the screen will weaken different frequency ranges. The end result is a so called meta-paper or frequency selective screen that can be used as a wall wallpaper in the rooms where we want to weaken specified frequency ranges. Innovation is the manufacturing of a selective screen for various frequency ranges. In accordance with the international classification of patents, the invention is classified into the group H04.

COBISS.SI-ID: 382912European project which included 10 partners from 5 countries was a part of Transnational program Central Europe. The main goal of the project was to enhance the awareness among all stakeholders in the paper-value chain, about the ecological loop of printed products and paper-based packaging. Another aim of the project was to provide tools for their efficient collection, reuse and recycling. It was shown how circular economy works in the paper sector, and the potentials for even further improvement were identified. Tools to measure and benchmark future potentials of closing the loop for graphic products at various stages, from eco-design to end-of-life solutions were suggested. Eco-design of printed products and packaging, systematic collection of paper for recycling adapted to each region are of the crucial importance for improving the quality of paper for recycling. A new method for assessment of paper based packaging recyclability was developed. The results of the project are presented in four guideline documents: Recyclability of Paper Based Products, Eco-design for Recycling: Criteria for Sustainability, Recommendations on Collection Strategies, Policy Recommendations and Guidelines. Results of the project, that promote sustainable use of paper-based products and packaging, reuse and recycling, lowering the quantity of waste, have important role in the public awareness, enhancing awareness at policy makers, among all stakeholders in the paper-value chain and waste management companies, as well as in higher education.
D.06 Final report on a foreign/international project
COBISS.SI-ID: 3154288A printing ink for irreversible temperature indicators with activation at low temperatures was selected as the winner of the innovation contest named “Rector's Award for the Best Innovation at the University of Ljubljana in 2015”. The innovation combines the knowledge of thermochromic composites and microencapsulation technology. The innovation can be used for temperature indicators in printed or in coated forms. By exposing the product beyond the allowed temperature limit, the indicator irreversibly changes colour and alerts to the improper handling of the product. The innovation is a result of cooperation between researchers of the Faculty of natural Sciences and Engineering (B. Boh Podgornik, B. Šumiga) and the National Institute of Chemistry (M. Klanjšek Gunde, K. Bašnec, M. Friškovec).

Object of the presented invention belongs to the field of secondary packaging for storing foods, for which it is desirable to control their temperature before consumption. The invention refers to the cardboard packaging made of a multi-layered cardboard, where the incorporated printed temperature sensor allows the end user to determine the appropriate temperature before food consumption. More precisely, it is a temperature (resistor) sensor, printed with the conventional or digital printing technology and is placed at the bottom of the smart packaging under the protective laminating heat resistant layer. Innovation is a printed temperature sensor, while the measurement system is based on conventional electronics. The sensor itself is not tied to the measuring system type, and it can be upgraded with a system for the radio frequency communication. In accordance with the international classification of patents, the invention is classified into the group B65D.
