"Colourful" Czech-Norwegian cooperation strengthened by the MODUS programme

The Norwegian Colour and Visual Computing Laboratory of the Norwegian University of Gjovik is a leading research institute in areas that are closely related to the administration, processing and reproduction of colour information in today's digital workflows. The Faculty of Chemical Technology has managed to establish successful cooperation with them. One of the outcomes has been successful reciprocal visits by the staff of both institutions.
In 2015, Ondrej Panák of the Department of Graphic Arts and Photophysics, the Faculty of Chemical Technology, visited the Norwegian department in Gjøvik for the first time (the NF-CZ07-INP-3-085-2014 project). With this individual mobility, the Czech department could identify areas for further development of cooperation. It was made possible to continue it through the institutional programme MODUS (NF-CZ07-MOP-3-2462015), which focused mainly on the exchange of staff from both partner universities. And so, another visit took place to the The Norwegian Colour and Visual Computing Laboratory at Norges Teknisk-Naturvitenskapelige Universitet in Gjøvik (NTNU) in Norway. This year, it was in May and June.
Joint research was born
One of the areas of common interest is gonio-spectrometric measurements of printed samples that exhibit different levels of gloss or change their colour with the change of the viewing angle. Petr Janíček and Jan Mistrík of the Institute of Applied Physics and Mathematics, Faculty of Chemical Technology, tested the possibility of using ellipsometer, which is available at the Institute, for the gonio-spectrometric measurements. Aditya Sole (NTNU) is developing a method to determine the characteristics of the appearance of such materials using a specially calibrated camera. However, he needs to compare his measurements with spectrometric measurements. During the visit to the University of Pardubice, reference samples were scanned at the Institute of Applied Physics and Mathematics using various techniques to verify the ability ellipsometer to obtain the desired values. A great challenge was to find an experimental procedure to measure highly diffusive samples using this device. In addition, the Department of Graphic Arts and Photophysics has also prepared sets of printed samples for further joint research.
Thesis consultations
The second common concern is the development of cooperation in teaching and research in the field of colour management. In May, Petr Nussbaum of NTNU prepared for students of the University of Pardubice a lecture entitled "Introduction to Colour Management", which aroused great interest especially among students majoring in Graphic Arts. Cooperation was also agreed on consulting our student’s thesis focusing on colour management of lightened up media.
Internship in Norway
During Petr Janíček and Ondrej Panák’s visit to Gjøvik, the data measured in Pardubice were analyzed and compared with measurements made in the Norwegian institution. As part of this internship, a seminar was jointly prepared for staff and students at NTNU on measurement and evaluation of colour samples whose appearance changes due to rotation or temperature. Besides Aditya Sole, Petr Janíček and Ondrej Panák, Nina Basic of the Swiss Institut für Metrology mad an appearance at the seminar remotely via conference call. The seminar thus enabled the parties to present the results of developing cooperation, which both parties are carrying on.
