This paper examines the impact of the CO2 laser parameters on the tensile strength, which is one of the most important properties of paper packaging in the process of cutting paper material. The study was performed on a paper material sample Fbb Board/Ningbo Spark C1S Ivory Board by examination of the influence of four independent variables: paper material grammage, cutting speed, laser power, and resolution on the tensile strength by using definitive screening design. Optimum process conditions of four variables that maximize the tensile strength were predicted and validated accordingly. Results confirm that laser power, paper material grammage, and cutting speed are the main process parameters that mostly affect the tensile strength. Besides individual parameters, two statistically significant interactions were obtained: laser power and cutting speed, and cutting speed and laser resolution. Maximum tensile strength values (20.37 N/mm) were achieved using the laser power of 60.6%, cutting speed of 3.24%, resolution of 2500 Hz, and a paper material grammage of 326.85 g/m2. With laser power at middle values and at a lower speed, a maximum tensile strength value can be obtained. Increasing the laser power and cutting speed will produce a slight lowering of tensile strength.

The subject of this paper is the development and design solution of an augmented reality application for marketing purposes. The main goal of the study is to examine the functionality of Unity software and Vuforia software development kit, as well as create an application that will allow the user to play video content using augmented reality technology. The application's primary goal is to give the user more information about the Company behind the Augmented Reality target image. The development of the application was preceded by research in the field of immersive technologies and software for Augmented Reality development. The aim of this research is to set up an intuitive system in the form of a mobile application that would identify the image and play and control the video content on the mobile device screen using Augmented Reality technology.

The consumer's interaction with packaging should be simple and intuitive. However, packaging is frequently designed in such a way that it is difficult to use, with text and labels that are difficult to see or understand. As a result, the prospective consumer may be discouraged from purchasing the product, or if the purchase has already been made, the ineffective handling of the packaging may result in a negative user experience, e.g. some users struggle to open the packaging. Due to the inability of the user to access the contents of the packaging, the user often experiences a feeling of frustration which may lead to accidents and injuries. This paper emphasizes the importance of cognitive ergonomics in packaging design. Cognitive processes, which involves how people think, make decisions and react, can be predicted, and lessons learned from studying these predictable responses can be integrated into good design.

The subject of this paper includes research into the possibility of using different waste paper materials for the production of new graphic packaging, in order to reduce the percentage of paper waste, give new life to waste paper materials, and reduce the production and use of virgin paper packaging materials. The subject of this paper also includes research into the possibility of using the FDM technique of additive manufacturing in the production of molds for casting, that is, the design of future paper packaging. The molding process is used to form the shape of paper pulp, while the forming process is used to form the shape of solid paper materials.

U radu je predstavljen način funk­cionisanja radnih tokova u grafičkoj proizvodnji i opisane su komponente koje su neophodne pri automatizaciji radnih tokova. Eksperimentalni deo obuhvata analizu softvera koji se koriste u okviru pripreme za štampu i zasnivaju se na manulenom ili automatizovanom načinu rada. Njihovim poređenjem izveden je zaključak o efikas­nosti uvođenja automatizacije u radni tok u okviru ode­ljenja pripreme za štampu.
