“…i) that was also graded as unacceptable but with just visible damage by one expert (N = 1). Both of the samples have folds parallel to the fiber direction which usually has better folding properties(Giampieri et al, 2011;Leminen et al, 2021). The damage to the top layer is less which can be seen in the previously mentioned sample figures.…”

Flatbed cutters are in increased demand and usage due to their developments in tool speed and size of the cutting area. The creasing tool on flatbed cutters are mostly creasing wheels as opposed to flat knives in die cutters. The wheel creases the paperboard in a way that can damage the top layer causing breaking in the printed surface visible after folding and sometimes even before. The end result can decrease the attractiveness of packaging and other creased paperboard products. This paper investigates the results of flatbed creasing of different types of printed paperboard and suggests possible solutions to the problem. Examined paperboards differed in grammage, grade, and thickness, and they were creased with different depth levels. The results indicated that some types of paperboard are not suitable for packaging even if they are adequate grammage. Furthermore, controlling the creasing depths can reduce ruptures of the top layer and improve final folding quality.

“…For cutting layout sheets a Z10 drag blade was used and a creasing wheel C203 with a diameter of 15 mm, a width of 0,7 mm, and a depth of a maximum of 1 mm. Which, according to previous research, is most similar in size of a die-cut creasing ruler (Giampieri et al, 2011;Huang and Nygårds, 2011;Leminen et al, 2021) The samples were creased in 3 depth levels: 0,5 mm, 0,7 mm and 0,9 mm with the measured force of 6,88 N, 10,2 N and 13,58 N respectively. The samples were named according to the variables presented in Table 2.…”

It is my great pleasure to introduce You the research papers of the Eleventh Symposium on Graphic Engineering and Design.With this proceeding we continue the works of previous symposiums which have been held biennial since year 2002.We're delighted that this international symposium has once again gatered a great number of participants from many countries as it became a tradition over the past 20 years.The papers include the achievements of researches in the field of technology and scientific areas relevant to graphic technology and graphic design. Through the work of the symposium GRID we continued significant scientific cooperation with educational institutions all over the world. With them we are continuing good cooperation which is the driving force for the creation and display of new developments, both individual and common. I want to thank everyone who participated with their paper and presentation in the Symposium. Your contribution is significant for the improvement of the Symposium on Graphic Engineering and Design GRID 22. The research achievements presented here are also valuable to the scientific and professional community and are highly appreciated.

“…The blanks produced are then folded to a final package shape, which are expected to have undamaged edges (Domaneschi et al 2017). Production of folding lines is also possible using other processes, for example, paperboard scoring (Leminen et al 2021), and several works mentioned below have examined different paperboard treatment methods for package forming. Of the creasing processes available, two are the most frequently mentioned in the studies reviewed.…”

“…Scoring can be done mechanically (e.g., by knife) or by laser, resulting in continuous or dashed cuts, which respond to folding differently (Mentrasti et al 2013). All four methods were studied by Leminen et al (2021), and the results were reported to differ as regards the dimensions of the folding lines made: creased grooves were much wider than scored ones, but their depths were still comparable. According to the study, the flatbed die-cutting process performs best with wider grooves in the matrix (Leminen et al 2019) and results in a lower force being required to fold the sample (see further sections).…”

Considerable research is ongoing, examining opportunities for substituting plastic packaging with more sustainable alternatives, and some encouraging results have been achieved. Coated paper and paperboard demonstrate promising performance; however, several serious drawbacks still need to be overcome. Recent research in this area is reviewed in the current work, including mechanical and machinery aspects of paperboard converting, as well as barrier properties of coated materials before and after processing. The main objective of the study was to establish how coated paperboard behaves during converting operations and investigate what changes in its properties occur, considering not only the convertibility of the material as a whole but also effects on substrates and coatings. The results of the literature review show that creasing, folding, and the presence of forming stresses severely damage barrier and pigment coatings even if the paperboard-based product is reported as having good oxygen and water vapour barrier or oil resistance after production. Thus far, most materials cannot fully match the performance of plastic packaging materials due to a noticeable reduction in barrier properties after converting. The work presents factors linking the convertibility of coated materials and their subsequent barrier properties as valuable knowledge to support future development of sustainable materials.
