Post press processes include various types of bonding and adhesives, depending upon the nature of adherends, the end use performance requirements and the adhesive bonding processes. Polyvinyl acetate (PVAc) adhesive is a widely used adhesive in the graphic industry for paper, board, leather and cloth. In this study, the enhancement of PVAc adhesion performance by adding different concentrations (1%, 2% and 3%) of silica (SiO₂) and titanium dioxide (TiO₂) nanoparticles was investigated. The morphology of investigated paper-adhesive samples was analyzed by SEM microscopy and FTIR spectroscopy. In addition, the optimal adhesion at the interface of paper and adhesive was found according to calculated adhesion parameters by contact angle measurements (work of adhesion, surface free energy of interphase, wetting coefficient). According to obtained surface free energy (SFE) results, optimum nanoparticles concentration was 1%. The wettability of the paper-adhesive surface and low SFE of interphase turned out as a key for a good adhesion performance. The end use T-peel resistance test of adhesive joints confirmed enhancement of adhesion performance. The highest strength improvement was achieved with 1% of SiO₂ nanoparticles in PVAc adhesive.

Experiential graphic design (XGD) has increased in importance over the past decade, with technological advances and a focus on user engagement. While the acronym XGD has been used for years, many practitioners prefer the older acronym, EGD, which stands for environmental graphic design. XGD, however, more accurately reflects the field’s scope, which combines multiple design disciplines to enhance user experience through the visual interpretation of ideas in physical spaces. The objective of this study was to perform an extensive bibliometric analysis of the existing literature on XGD topics across a wide range of spatial contexts, with particular emphasis on open public spaces and enclosed architectural environments, structured around four research questions related to the following: (1) foundational studies and the evolution of the literature, (2) the main keywords and research trends, (3) XGD application environments, and (4) XGD’s key roles. The methodology involved analyzing 245 records on the XGD topic from the Scopus, Web of Science, and Google Scholar databases, following the preferred reporting items for systematic reviews and meta-analyses (PRISMA). Based on a comprehensive review of the literature, this study offers a general overview of XGD, exploring its applications across different built environments. In addition, it pairs theoretical concepts with practical examples to demonstrate XGD’s key roles, highlighting current trends, future developments, and the need to establish educational frameworks in the XGD field.

This paper contributes to eco-efficient and sustainable book binding production. Higher book binding manufacturing efficiency—with less waste and reduce energy consumption—has been achieved with higher inputs of natural biodegradable sources into graphic arts materials through the eco-labeled paper grades and the use of eco-advanced adhesive system solutions. Nowadays, scientific sources on non-toxic polymers and resins, combined with current scientific knowledge and production development, are closely related to sustainability. Hence, advanced and improved adhesive system solution technologies should fulfill the needs of suppliers and customers who are involved in the International Framework for ISO/TC130 workflows. These strategic partnerships provide possibilities in the context of “closed-loop recycling models”, which spark and advance the discussions of stakeholders. It is very important that the novel engineered biodegradable adhesive system solutions provide productivity-increasing and cost-effective solution performances by saving money and improving the performed binding activities. Without doubt, the task of the scientific community is to continue to provide responsive and comprehensive approaches to fulfilling stakeholders’ specific needs through standardized quality assurance, with the emphasis on book-binders.

Adhesive modification with nanoparticles affects multiple adhesives properties, making it essential to evaluate and compare changes across all key characteristics—existing positive and limiting properties. This study investigates the impact of silica (SiO₂) and titanium dioxide (TiO₂) nanoparticles on the elasticity and aging resistance of PVAc adhesive. Tensile properties were determined according to ISO 527-3:2018, with Young’s moduli of elasticity $\left({\rm E}\right)$, and stress–strain curves for neat PVAc, nano-SiO₂ PVAc, and nano-TiO₂ PVAc adhesive. Material toughness ($U_T$), failure stresses $\left({\sigma }_f\right)$, and failure strains $\left({\epsilon }_f\right)$ were also calculated. After UV exposure (0, 48, and 96 h), according to ISO 9142:2003, samples were characterized by Fourier-transform infrared spectroscopy (FTIR). Analysis of variance (ANOVA) was performed to determine if there is a statistically significant difference in material toughness between neat PVAc and nano-modified PVAc adhesives, as well as changes in FTIR spectra of paper–adhesive samples before and after UV exposure. The Bonferroni post hoc test was used to identify specific group differences. The results showed that SiO₂ nanoparticles improved PVAc elasticity by 9.15%, while TiO₂ nanoparticles reduced elasticity by 44.47%. FTIR analysis revealed similar behavior in both nano-modified and neat PVAc adhesives after UV exposure, indicating that aging resistance was preserved with the addition of SiO₂ or TiO₂.

Adhesive bond strength depends on adherend, adhesive and interphase zone. Adhesive joint includes bonded areas or binding edges across bonded layer. Research of adhesive bond strength focuses on understanding the properties of bulky paper associated with formation of the interphase and adhesive joint failure mode. The key contributors of good adhesive bond strength are paper rough surface necessary for mechanical interlocking, adequate adhesive flow and adaptationfor intimate interaction and acceptable adhesive setting time. Change of parameters has strong influence on final adhesive joint formation. Adhesive bond strength assessment involves adhesive joint strength determination. Pull test method is used for adhesive joint failure mode characterization. Furthermore, adhesive joint strength results directly explain bulky paper bind ability by perfect binding technique. FOGRA recommendation rating directly confirms paperback binding quality with bulky paper application. Understanding of bulky paper bind ability involves comprehensive physiochemical knowledge of material (paper, adhesive). In addition, this binding technique is more unique because of its interest for adhesive joint formation.
