“…The use of alternative materials in papermaking offers a more sustainable and economically viable solution for reducing the consumption of wood pulp and minimizing the use of virgin fibers. Furthermore, using recycled and non-woody plants in paper production offers more advantages, like providing an environmentally friendly alternative to conventional wood-based paper manufacturing, reducing deforestation and CO 2 production [5,6]. Moreover, it allows for the reuse and recycling of paper, contributing to waste reduction and resource conservation [7].…”

“…Ensuring an even density in the paper is influenced by various parameters such as the pulp preparation technology, equipment, and selection of optimal raw materials [13]. The availability of raw materials, especially non-wood materials, is a challenge due to the pressure on forests and the decline in capacity utilization in the paper industry [6]. Additionally, the influence of the fiber type on the vapor barrier properties and migration to foods needs to be considered for food packaging applications.…”

This study aims to investigate the feasibility of using paper made from eco-friendly recycled and non-woody plants in graphic technology, particularly in offset printing. Instead of changing the composition or modifying the surface properties of the paper, the focus was on enhancing the print quality by modifying the printing ink. By modifying the printing inks, the quality of the prints on recycled and non-woody paper can be optimized, which in turn reduces the need for paper made from primary fibers. This approach can expand the use of alternative materials in graphic technology and design. The objective was to optimize the print quality on these sustainable materials. Five types of uncoated paper were used, with high-quality uncoated offset paper based on virgin fibers serving as a reference. Laboratory tests of the basic and surface properties were carried out to measure the paper quality parameters that are important for offset printing. The influence of the paper composition on its optical and colorimetric properties was also investigated. The interaction between the selected papers and offset inks was examined through measurements of adhesion parameters and ink transfer, i.e., the paper’s ability to accept the ink. To enhance the applicability of the investigated papers as printing substrates in the graphic industry, SiO2 and TiO2 nanoparticles were added to the offset inks. The influence of the paper composition on the colorimetric properties of the prints was also investigated. The print uniformity, as an important quality characteristic, was determined by measuring the mottling index. The research findings indicate that incorporating SiO2 and TiO2 nanoparticles into offset inks can enhance the interaction between the paper and ink, leading to improved print quality. This study provides new perspectives on the possibilities of using recycled and non-woody plant paper in offset printing without significantly compromising the quality of the print.

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.

“…Extensive research has been conducted on residual straw of wheat, barley and triticale collected after the crop harvest, and it has shown that cereal straw is a valuable raw material for the paper industry (Plazonić, Barbarić-Mikočević & Antonović, 2016;Plazonić, Barbarić-Mikočević & Džimbeg-Malčić 2014a;Plazonić, Barbarić-Mikočević & Džimbeg-Malčić 2014b). Papers with an addition of cereal pulp are mostly used for secondary packaging (Kurek et al, 2022) which often contain some kind of printed content: text, barcodes, logos and other types of graphics. This research focuses on evaluating the quality of ink-jet printed text patterns for two different typefaces.…”

Traditional papermaking is based on the use of an aqueous suspension consisting of cellulose fibres obtained by processing wood, non-wood plants or waste paper. With growing environmental concerns regarding deforestation and CO2 production, the paper industry has been always looking for new sources of non-wood pulp that would produce papers of similar quality to those made from wood pulp. Cereal straw from wheat, barley or triticale crops that remains on fields as a residue after grain harvesting has proven to be a good substitute for virgin wood fibres needed in the production of recycled paper. In this study, the quality of printed text on recycled paper with added straw pulp is evaluated mainly based on the line and edge characteristics of the printed letters. For this purpose, three types of laboratory paper substrates were first prepared using recycled wood pulp with the addition of 30% wheat, barley, or triticale straw pulp. The same letter pattern was printed with black ink on each paper substrate at a standard size of 12 pt with two common typefaces: Arial and Times New Roman. The quality of the printed letters was assessed through the measured print quality parameters such as blurriness, raggedness, fill and contrast. The resulting measurements were compared with the results obtained on the reference and control samples made exclusively from recycled wood pulp as a substrate from laboratory and commercial production. In terms of fill and contrast values, the uniformity of lines printed on the recycled papers with added straw pulp is the same or very similar to the reference and control papers. Letters printed in Arial (sans-serif) typeface show slightly better reproduction quality than letters printed in Times New Roman (serif) typeface. The measured parameters blurriness and raggedness of all laboratory-made paper substrates (with and without straw pulp) had similar values between 0.17 mm and 0.20 mm, resulting in a very similar reproduction quality compared to the reference paper substrate.
