Previous research reported on the significant role that packaging visual elements play in food context. Still, little is known about how typeface design can influence consumer expectations and stimulate their food choices in the case of spices. Thus, the present study aimed to investigate the influence of packaging typeface on the consumers’ selection of spice and their expectations of its quality. The first part of the study was an online experiment in which participants were presented with packaging that differed in visual elements, namely typeface (sans-serif, handwritten) and ingredient depiction (photo, illustration, without depiction). The second part of the study was conducted in a laboratory setting where participants viewed packaging that varied in typeface and flavor (red pepper, dried basil), and explained their reasons for selecting a particular packaging. The results showed that typeface influenced the participants’ choices and their expectations. The first experiment revealed that the effect of the typeface occurs only in the presence of ingredient depiction (either photo or illustration), while the second experiment indicated that the participants’ expectations of spice quality were based on the perceived typeface legibility. This implies that a legible typeface on food packaging can be a useful tool for attracting consumers’ attention and stimulating their choices of food products.

In order to increase the sustainability of paper or board production, it is desirable to use recycled fibers as much as possible. Microorganisms are in a smaller or higher amount present on the surface of paper or paperboard, so they are also present in the paper pulp or on the cellulose fibers. The purity of the mentioned fibers is important for obtaining a quality raw material that is health conforming. The aim of this study is to determine the microbiological quality of recycled fibers obtained by recycling of paper and paperboard intended for the manufacture of packaging products. Samples were in an average microbiological environment without food exposure. Quality of recycled fibers was studied through the total number of bacteria and determined for different recycled samples. The total number of microorganisms was estimated by both the disintegration and smear method. Results showed that only the disintegration method was suitable for the evaluation since the smear method did not produce any results. Moreover, the disintegration method was suitable only for the determination of bacteria alone, since no growth of molds or yeast occurred. In addition, the influence of paper composition, paperboard coatings and recycling methods on bacterial growth is demonstrated. The number of bacteria obtained on recycled fibers is affected by the presence of nanoparticles in coatings (Zn, Si and Al), as well as by the presence of different components in the base paper.

In the label and package printing industry, many methods are used for the application of a metallization on a substrate for graphical purposes. By applying metals like aluminum and copper-zinc on a substrate, outstanding visual effects can be achieved. It is shortly discussed why metallic surfaces appear different compared to non-metallic surfaces and what kind of terms can be used to describe a metallic appearance. Further, different printing methods for metallization are categorized according to the form of the initial metallic material used for the given printing method. It is distinguished between methods using metallic pigments with and without printing ink and metallic foils. Special attention is paid to the printing methods using aluminum pigments in printing ink. The appearance influencing properties of aluminum pigments are listed and different methods of their production are described. The influence of the different ink systems on aluminum pigments and printing methods using these inks are outlined. Furthermore, printing methods using metal effect pigments not incorporated in an ink such as bronzing and the EcoLeaf technology are shortly explained as well as different metallization methods using foil directly involved in the printing process like foil fusing, foil transfer and foil stamping methods.

Keywords: metallic pigments, metallization, metallic effects, print

Progress or regression in the practice of immersive journalism? Immersive storytelling in the productions of the Samsung VR platform between 2015 and 2020

Journalism has undergone countless changes in recent years, especially since the emergence of the network of networks. As digital technologies have gone from strength to strength, new ways of doing journalism have also gained traction, focusing on the potential offered by “going digital”. This perspective goes hand in hand with another linked to virtual reality (VR) and 360-degree video, with additional technical characteristics. Since 2010, there has been talk of so-called “immersive journalism”, which uses the above-mentioned technologies to narrate events, introducing a perspective into journalism that breaks with the classical concepts of working with information and making it available to the viewer, who now becomes an immersive user. This is the context of the present investigation, which focuses on the change of immersive journalism over the last five years. To this end, 1713 pieces available on the Samsung VR platform are analysed. The results reveal that there have been some changes in terms of production; however, in narrative terms, when it comes to reporting reality, the only evident change has been the way in which the functions of immersive storytelling elements have been updated.
