The final editing and production of the September issue of the Journal were done during and immediately after the International Research Conference of iarigai in Stuttgart. We are still under the impression of many interesting and quality presentations, and now we are expecting new papers for publication in the Journal.

In the present issue, the original scientific paper on the nonlinearity of screen printed electroluminescent panels stands out among the three articles. By measuring the properties of electroluminescent panels under different conditions, especially at low and high voltages, and in dark and light environment, the authors explain their operation and also open up new possibilities in the study of optical and radiation sensors. The second paper deals with the more traditional area of maintenance strategy of a printing press, where we can improve the knowledge and risk management of the installed equipment in the print house, by the implementation of an appropriate approach. In the third article, the authors present a study of the effect of starch addition in the paper coating formulation on the pitting, which has a significant effect on the surface of coated paper and thus on the quality of the print.

The editor Markéta Držková (marketa.drzkova@jpmtr.org) in the Topicalities of this issue prepared an overview of the new and updated ISO standards, and short info on the results of the survey on system integration – one of the expected topics at Drupa 2020.

Among the new books, she reviewed new publications, among which there is highlighted book on multisensory packaging, and introduction of new and partly refurbished work – a series of 26 books in the field of digital and print media design. Although it is in German, some of the contents of the same authors have already been published in English in the past, so we can hope that this set of textbooks and workbooks will also be available in English in the future and thus used in the wider international area.

The three doctoral theses selected differ in content as well as geographically, thus providing insight into the breadth of the research area we identify with.

Robert Wiesenberger successfully defended his thesis at Columbia University, New York, USA. He researched and presented the life and work of Muriel Ruth Cooper, who worked as a graphic designer, educator and researcher at MIT, as well as her grandness and impact on major turning points in the press and media design in the twentieth century.

Mima Kurian defended her doctoral thesis on 3D printed bone-like composites at Victoria University of Wellington, New Zealand. Using the appropriate material based on chitosan and calcium carbonate, she produced 3D structures with a nano and macro-pores using synthetic biomineralization method, resulting in material comparable to the bone and tested its properties.

At Karlstad University, Sweden, Sofia Thorman defended her doctoral thesis in the field of absorption and distribution of ink in flexography. She investigated the interactions of printing ink with the base substrate as well as with the previously printed surface in flexography and related causes of print non-uniformity. She has also tested the new staining method in other fields and has proven its usefulness for determining water-moisture interference in lithographic offset printing.

Announced changes to the Journals editorial team are already underway, though they have not yet been finally adopted and implemented. You are invited to take the opportunity to publish the results of your research work in the Journal. The call for papers is constantly open. We would also appreciate your tips on interesting events, new books or theses from the fields covered by the Journal, aimed at iarigai members, subscribers to the Journal and all other experts reading and using it as a reference in their research activities.
